Cockpit_active was latched inside ship_render_player_ship(), which only
runs when Viewer_obj is non-null. External, chase, warp-chase, topdown,
free-camera and dead views all null Viewer_obj, so the flag froze at its
last cockpit-view value and cockpitinactive HUD gauges vanished. It was
also read before being written each frame (by the show-ship check and the
shadow helpers), so those decisions lagged a frame on any transition.
Replace it with three functions computed on demand:
- ship_cockpit_enabled(sip): the ship has a cockpit model and cockpits
aren't disabled; used by the Show_ship_only_if_cockpits_enabled checks
- ship_render_player_cockpit(sip): the above, outside topdown view;
replaces three duplicated copies of that expression
- ship_render_player_cockpit_active(): whether the viewer's cockpit is
being rendered this frame; used by the HUD cockpit-view-choice checks
With the predicate correct, the VM_CHASE special cases added for #4804
are no longer needed and are removed. In chase view, cockpitinactive
gauges now also respect pop-up state, No_ets, and setRenderOverride,
which the early return in HudGauge::canRender() used to bypass.

Follow-up to #7635.
Pass the firing bank explicitly through weapon_create() and beam_fire()
instead of searching the ship's banks by weapon class, which could
attribute substitution patterns to the wrong bank. Factor the
substitution logic into get_weapon_substitution_tuple() and only apply
linked/dual-fire pairing to ship-level fire, not turret fire. Skip
substitution on multiplayer clients, since the server already resolved it.
Derive turret bank indices from the weapon slot being fired rather than
the turret's bank cursor, so ammo and substitution state are tracked on
the bank that actually fired. Previously a single-selection turret could
consume ammo from a bank it never fired, and non-ammo turrets (whose
cursors stay at -1) would have skipped substitution entirely.
Use the Player_ship object flag rather than Player_obj in
ship_secondary_bank_can_dual_fire() so the server and clients agree on
dual fire for remote players, and guard ship_secondary_has_ammo() against
a negative bank index.

Ship's implicit move operations compiled but were semantically broken in
two ways: moving copied the subsys_list sentinel's links verbatim,
leaving the bookend nodes of the intrusive subsystem list pointing at
the old sentinel address; and the raw owning warpin_effect /
warpout_effect pointers were copied without nulling the source, so a
vacated Ships[] slot aliased live WarpEffects that ship::clear() (on
slot reuse) or ship_close() (which walks every slot) would delete out
from under the destination ship.
Fix both at the member level so the compiler-generated moves are
correct by composition:
- Add ship_subsys_sentinel, derived from ship_subsys, whose move
operations re-link the bookend nodes (handling the null-linked,
self-referential-empty, and populated source states) and leave the
moved-from sentinel as an initialized empty list. Copying is
deleted. Public inheritance keeps &ship::subsys_list convertible to
ship_subsys*, so list_init, GET_FIRST, and every other call site is
unchanged.
- Convert warpin_effect and warpout_effect to std::unique_ptr. The
delete-and-null blocks in ship::clear(), ship_close(), and
ship_set_warp_effects() collapse into reset(); call sites that borrow
the pointer into a raw local now use get().
With the members handling themselves, declare ship's special member
functions: defaulted default constructor and moves, deleted copies
(previously implicit via the unique_ptr members, now stated intent).
The moves are deliberately not declared noexcept because members like
SCP_map and std::deque do not have standard-guaranteed nothrow moves;
the computed exception specification is used instead.

* avoid undefined behavior from UNREACHABLE on reachable code paths
UNREACHABLE expands to __assume(false) / __builtin_unreachable() in
release builds, which is undefined behavior if the code is ever actually
reached. Many UNREACHABLE sites only guard against unexpected-but-
possible runtime states (values from tables, mission/save files, network
packets, scripting, or user input), so reaching them should degrade
gracefully rather than invoke UB.
Replace UNREACHABLE with Assertion(false, ...) at all such sites. It
still pops an error in debug builds, but in release it is a harmless
no-op that simply falls through to the following code. Sites that are
genuinely unreachable by local invariants (e.g. a switch over a bounded
random number) are left as UNREACHABLE.
A few converted sites had no safe fall-through -- an uninitialized read,
null dereference, or null call would have followed -- so they also get a
minimal recovery: initialize the value, guard the dereference, return
early, or skip the offending item.
Where the converted site was a simple guard of the form
if (x) { Assertion(false, ...); return; }
hoist the check onto the invariant instead:
Assertion(!x, ...);
if (x) { return; }
This states the expectation directly and shows the offending value in
the debug popup, while keeping the same graceful runtime degradation.

* addendum
After consultation with Lafiel, use UNREACHABLE in situations that are effectively impossible even if not provably impossible. UNREACHABLE = "this shouldn't ever happen"; Assertion = "if this ever happens, it's a coding error". Also fix a few other sites and change a couple to Warnings.

* use std::move() for local variables that are copied but not reused
Addresses ~140 Coverity "Variable copied when it could be moved"
defects across 74 files. Every std::move() targets a local variable
whose value is consumed by push_back, emplace, assignment, lambda
capture, or a function call and is never read again afterward.

1. Modify `ship_get_subsys_for_submodel` to use the subsystem indexer. This changes the operation from O(n) to O(1) and also allows the function to work with turret gun barrels.
2. Add an `isValid` check to `ParticleSource::finishCreation` to prevent unknown state from being accessed if the source is not valid.
3. Tweak `EffectHostTurret` and make sure it works for fighter beams.
4. Prevent `createOnTurret` from running on submodels that are not turrets.

* Add Mod Option to Limit 'Show Ship' when Toggling Cockpits
FotG uses cockpits and 'show ship', and also provides a way for players to toggle off cockpits. Unfortunately, if the player disables cockpits, 'show ship' still appears and looks very odd (since it appears the player is flying a ship with a hole in the center where the cockpit would be). Other mods have made entire ships with their cockpits, but FotG needs to use 'show ship' to match team colors and moving external ship animations.
This PR adds a game_settings option that allows mods to set to only use 'show ship' if cockpits are enabled.
Tested and works as expected.

This was motivated by the recent Coverity report. Coverity noticed that a few of the copy assignments could be replaced by move assignments, but on further investigation one copy each in `ship_weapon_check_collision()` and `beam_collide_ship()` can be entirely removed, another either/or copy in each can be replaced with an either/or pointer assignment, and a few copies can be done only when needed. Another vec3d copy (`hit_dir`) can be replaced with a vec3d pointer; it is no longer modified locally, so there is no longer a need to keep a local copy.

Use a simpler, more robust, and more correct method of sharing the fire direction among beams: replicate the actual beam vector for all firing points. This further cleans up and simplifies the beam firing code and also clarifies some vector math.
Some of the `frand_range` calls were used for integer calculations, so we can use `Random::next` now.
This also reduces the number of C-style casts in the codebase.
