refactor: remove verified dead code across data, UI, and resources (#680)

* refactor: remove unused dead code across data, UI, and resources

* fix: resolve dangling references left by dead-code removal

Restore empty object Motion (braces required) and remove the 12 stale
test usages that still called the now-deleted production symbols:
- ServerStoreTest: removeServer/switchToServer tests
- ServerEndpointTest: isCleartext assertions
- ConnectViewModelTest: onHostChange/onPortChange tests + 3 dropped R.string refs
- SettingsViewModelTest: renameProfile tests + clearNavigateToLogin
- E2eIntegrationTest: previewSkill tests + onHostChange/onPortChange calls

Verified locally: compileDebugUnitTestKotlin + 48 tests pass.

* fix: remove unused imports flagged by ktlint

Drops 4 no-longer-referenced imports left by the dead-code removal:
- HermesApiService: SkillScanResponse (scanHubSkill removed)
- ServerEndpointTest: assertFalse, assertTrue (isCleartext assertions dropped)
- SettingsViewModelTest: assertFalse (rename tests removed)
