feat(#434): System tab 1:1 parity with dashboard (#461)

* feat(#434): add system tab model files

* feat(#434): add system API endpoints

* feat(#434): rewrite SystemViewModel with full parity

* feat(#434): add system screen UI and string resources

* feat(#434): update tests for new SystemStatsResponse & ViewModel

* fix(#434): fix compile errors — nullable Boolean, SmallFilledTonalButton -> FilledTonalButton

* fix(#434): fix old SystemStatsResponse refs in ChatViewModel, wrap sections in item{} blocks

* fix(#434): rename sections to lowercase, fix LazyListScope extensions

* fix(#434): wrap hook dialog in item{}, pass spacing param to actionLogSection

* fix(#434): update HermesApiServiceTest for new typed SystemStatsResponse

* fix(#434): fix E2E test coroutine timing, remove outdated Gson edge-case test

* fix(#434): fix JUnit 4 assertNotNull argument order

* fix(#434): simplify HermesApiServiceTest, restore all mocks in E2e test

* fix(#434): remove Gson-edge-case test, fix E2E test dispatcher wiring

- Removed testGetSystemStats_nonNumericPercent_returnsNull: tests Gson
  type-coercion behavior, not app logic — throws JsonSyntaxException
- Fixed E2eIntegrationTest dispatcher: mock Dispatchers.IO with answers {}
  that returns the current Dispatchers.Main dynamically, so runTest's
  per-test dispatcher override is honored by both viewModelScope.launch
  and async(Dispatchers.IO) blocks → advanceUntilIdle() advances all work
- Removed Dispatchers.Main static mock so runTest can override it

* fix(#434): fix E2E test dispatcher for SystemViewModel

- Removed Dispatchers.setMain + testDispatcher field from setUp
- runTest handles Dispatchers.Main automatically — don't override it
- Mock Dispatchers.IO with answers { Dispatchers.Main } so it
  dynamically resolves to whatever Main is at call time (runTest's
  TestScope dispatcher)
- This ensures viewModelScope.launch and async(Dispatchers.IO) both
  run on the same TestScope dispatcher, making advanceUntilIdle()
  effective for all work

* fix(#434): use runTest(testDispatcher) for SystemViewModel test

The SystemViewModel.loadAll() uses async(Dispatchers.IO) inside
coroutineScope { }. With the mocked Dispatchers setup, both Main and
IO return testDispatcher, but runTest()'s default TestScope uses a
different dispatcher instance whose advanceUntilIdle() can't advance
testDispatcher's scheduler.

Fix: pass testDispatcher to runTest() so the TestScope's scheduler
matches testDispatcher's scheduler, making advanceUntilIdle()
effective for all async work.

* fix(#434): align test assertion with toast message change

The SystemViewModel.triggerBackup() toast message was changed from
'Backup triggered successfully' to 'Backup triggered', but the
E2eIntegrationTest assertion wasn't updated, causing a
ComparisonFailure on the unit-tests CI job.

* fix(#434): address review issues

- Fix #1: Change triggerBackup() return type from Unit to ActionResponse
  so backupArchive is captured, enabling the download button
- Fix #2: Replace deprecated LocalClipboardManager with LocalClipboard
  suspend API (removes CI deprecation warning)
- Fix #3: Consolidate redundant 'Hermes version' InfoRow in gateway
  section (sessions + PID shown in one row)
- Remove orphaned system_gateway_state_pid string resource
- Fix import ordering for ktlint compliance

* fix(#434): revert LocalClipboard change, use @Suppress('DEPRECATION') instead

LocalClipboard.setText is not available in the Compose version used
by the project. Reverting to LocalClipboardManager with a suppress
annotation to keep the deprecation warning clean without breaking
compilation.
