fix(javascript): omit self-referential static references with disclosure (#1157)

* fix(javascript): omit self-referential static references with disclosure

A bundled module that requires its own key (`r(50)` inside webpack
module 50) resolved, through the static-reference composer, to its own
module node. The resulting self-referential imports edge failed result
validation and lost the entire analysis ("Result schema rejected 1
issue ... (custom)"). This is the same invariant as #1146; #1152 fixed
the bundler async-chunk composer, and this is the remaining adjacent
composer.

Skip a reference whose resolved target is its own source, count it, and
disclose the omission the way #1152 discloses async-chunk references.
Sibling requires are kept.

* refactor(javascript): share the self-reference omission disclosure

The self-import (#1130), async-chunk (#1152) and static-reference
disclosures repeated one sentence template in three composers, and the
new test repeated the analyze-and-check sequence of its neighbour. That
put jscpd at its 2.5% threshold. Share the template through
selfReferenceOmissions with identical wording, and share one test helper
for the graph-wide self-reference invariants.
