Merge feature/parallel-ui-tests: parallel UI tests with fail-fast rewrite

Enables parallel UI test execution via per-session data isolation:
- Each test class gets a unique session ID (UUID) for isolated UserDefaults
  and in-memory SwiftData containers — no shared on-disk state
- Rewrote all 60+ UI test files following fail-fast TEST_RULES patterns
  (2s default timeout, no sleep, no coordinate taps, no retry loops)
- Added missing accessibility IDs to MonthView, YearView, onboarding pages
- Added Next buttons to onboarding flow for reliable programmatic navigation
- Added ParallelUITests.xctestplan with class-level parallelism

+# UI Test Rules
+
+These rules are non-negotiable. Every test, every suite, every helper must follow them.
+
+## Element Interaction
+1. **All elements found by accessibility identifier** — never `label CONTAINS` for app elements
+2. **No coordinate taps anywhere** — `app.coordinate(withNormalizedOffset:)` is banned
+3. **Use screen objects for all interactions** — test bodies should read like user stories
+
+## Timeouts
+4. **`defaultTimeout` = 2 seconds** — if an element on the current screen isn't there in 2s, the app is broken
+5. **`navigationTimeout` = 5 seconds** — screen transitions, tab switches
+6. **No retry loops in test helpers** — tap once, check once, fail fast
+
+## Independence
+7. **Every suite runs alone, in combination, or in parallel** — no ordering dependencies
+8. **Every test creates its own data via fixture seeding in setUp**
+9. **No shared mutable state** — no `static var`, no class-level properties mutated across tests
+
+## Clarity
+10. **One logical assertion per test** — test name describes the exact behavior
+11. **`XCTFail` with a message that tells you what went wrong** without reading the code
+12. **No `guard ... else { return }` that silently passes** — if a precondition fails, `XCTFail` and stop
+
+## Speed
+13. **No `sleep()`, `usleep()`, or `Thread.sleep`** in tests — condition-based waits only
+14. **Target: each individual test completes in under 15 seconds** (excluding setUp/tearDown)
+15. **No swipe loops** — if content needs scrolling, use `scrollIntoView()` with a fail-fast bound
+
+## Parallel Safety
+16. **Each test process gets a unique session ID** — `UI_TEST_SESSION_ID` isolates UserDefaults and SwiftData
+17. **In-memory SwiftData containers** — no shared on-disk state between parallel runners
+18. **Session-scoped UserDefaults suites** — `uitest.<sessionID>` prevents cross-test contamination
