fix(config): name DeepSeek's Anthropic-compatible endpoint distinctly (CW-7408)

Both bundled DeepSeek descriptors were labelled "DeepSeek". So the desktop's
Default model, Add provider and key rows had to tell them apart with raw
ids ("DeepSeek · deepseek", "DeepSeek · deepseek-anthropic"), which a member
can't interpret. The deepseek-anthropic row is now "DeepSeek (Anthropic
API)". Its web label already read "DeepSeek Anthropic". The providers-export
golden carries the same label. The row is not selectable in the TUI
provider list, so the TUI picker is unchanged.

Verification on this tree (main be980da403, after the 0.10.2 squash),
shared with the CW-7406 settings copy commit, which touches disjoint
files:
- nextest, the whole codewhale-config and codewhale-localization packages
  plus TUI settings, provider, deepseek, descriptor, config view and
  schema tests: 2304 passed, 0 failed.
- npm test: 547 Node tests (540 passed, 7 skipped, 0 failed) and
  772 Vitest passed. npm run check:web: exit 0. The web prebuild output is
  unchanged.
- Not run: the desktop menus against an Engine built from this tree.
