fix: stabilize invite modal URL preview tests against jsdom event changes

- Convert two flaky userEvent.type()-based tests to fireEvent.change() with
  fake timers to avoid jsdom 29.1.1 incompatibility with email input events
- Replace waitFor polling (which hangs under fake timers) with synchronous
  assertions after advancing fake timers past the 500ms debounce threshold
- Fix lefthook frontend-lint and frontend-type-check hooks to use full paths
  for npm and npx so git hooks resolve the binaries in all environments
- Unblocks Renovate jsdom minor update (29.1.0 -> 29.1.1)
