test(W7c): ship-apple-gate matches its gates on meaning, not capitals

W7c (t06 #19). One test file.

Removed assertion groups:
- "A genuine blocker may require a safety or named documentation-risk
  decision" and "routine interactions and blocking decisions above" sentence
  pins. Invariant: routine release authorization never waives a blocking
  safety/docs decision. Remaining protection: kept free meaning check
  `/stop for that decision rather than treating release authorization as a waiver/i`
  plus `/named documentation-risk exception before distribution/i`.
- Full-sentence "in `read-only` mode against the selected release source".
  Invariant: the docs preflight is read-only. Remaining protection: kept free
  check on "`read-only` mode".

Loosened (case-insensitive, kept): apply-only-to-repository-landing scope
line, CLASSIFY-before-credentials (credential boundary), never abort a store
release over branch topology (demonstrated failure), two routine interactions
(numeric limit), stop-for-decision (consent/stop line).

Kept unchanged: manifest trigger routing, Apple read before the branch gate,
byte-exact branch gate appearing once, docs preflight before the
authorization moment, fastlane/iris/appPriceSchedules command anchors,
stale-wording bans. No gate-tier E2E covers the Apple adapter, so every
invariant keeps a free check here.

Cosmetic pins dropped: capitals on ONLY / CLASSIFY / STOP.

Mutation log: .context/mutation-ship-apple-gate.md (14 mutations, 0
unexpected: 2 reorders, 1 marker and 6 safety mutations red; 5 rewordings green).
