fix(tests): repair hero-strip and telegram-test-locale assertions after R3a

Two test-contract fixes for fallout from concurrent R3a contributors:

- hero-strip.test.tsx — collapses the two onAskCoach forwarding tests
  into a single regression guard that asserts the inline Health Score
  card Ask-the-Coach button stays retired and the hero strip's
  action-row button carries the affordance.

- telegram-test-locale.test.ts — the route's POST handler takes zero
  arguments (apiHandler wraps an async () => function). Drops the
  Request argument from all seven call sites.
