fix(suggested-fix-pending): apply PR #156 review fixes

- Page-level Resolve patches applied_pending → applied_success before
  opening the resolution flow, so resolved sessions don't carry a
  provisional pending fix.
- Page-level Escalate intercept now catches applied_pending in addition
  to verifying/partial; intercept copy generalized from "Verifying state"
  to "still needs an outcome."
- PendingBanner gains a Dismiss action, matching the PR body and the
  backend's allowed pending → dismissed transition.
- resolution_note_generator and escalation_package_generator system
  prompts no longer include real-looking pending examples (anti-parrot
  guardrail compliance).

Verified via Docker: prompt anti-parrot 2/2, suggested-fix outcome suite
21/21, frontend tsc -b clean, npm run build clean.
