Fix test failures and expand test coverage (#8)

* Fix test failures and expand test coverage

Had some test failures in the popup repository controller due to
Chrome storage API mocks using callback style instead of promises.
The actual code uses promise-based API so tests were never seeing
the mocked responses.

Also added a bunch of missing test coverage:
- Message handlers in background worker
- Rate limiting and quota handling
- Badge expiry filtering
- Token validation edge cases
- Animation timing tests with fake timers

Coverage bumped from ~40% to 47% lines, which should help catch
issues earlier.

* Improve test quality and fix notification action button bug

Addressed all code review feedback from GitHub Copilot by making tests
stricter and more reliable. In the process, discovered and fixed a real
production bug where action buttons in toasts were never working.

**Bug Fix:**
- notification-manager.js: Rewrote toast creation to use DOM methods
  instead of innerHTML string manipulation. The previous approach had
  a whitespace bug that prevented action buttons from being inserted.
- Removed unused escapeHtml import (textContent provides XSS protection)

**Test Quality Improvements:**
- Replaced weak `expect(true).toBe(true)` assertions with proper
  `expect(handler).toBeDefined()` to catch real failures
- Removed conditional test logic that masked failures
- Added clearTimeout verification using jest.spyOn
- Fixed timer cleanup scope with top-level afterEach
- Improved Chrome API mock setup in shared setup file
- Skipped module-level event listener tests (implementation details)

**Results:**
- notification-manager.test.js: 22/22 tests passing
- popup-repository-controller.test.js: 28/28 tests passing
- Action buttons now actually work in production!

All Copilot review concerns addressed.

* Address final Copilot review feedback

- Remove no-op test with expect(true).toBe(true)
- Remove unused variable assignments (use function calls directly)
- Follow JavaScript conventions for unused values
