chore(cleanup): delete nine dead components, orphaned i18n keys and unused deps

[4gray]

Summary

• Deletes nine verified-dead components (~4,800 LOC) orphaned mostly by the EPG timeline rework (feat(epg): rework live EPG panel into a horizontal timeline #1102), each re-verified to have zero class references and zero selector usages outside their own files.
• Removes their barrel exports, 18 now-orphaned i18n keys from all 18 locale files, dead CSS selectors targeting the deleted elements, and four unused dependencies from package.json.

Changes

Deleted components

• EpgListComponent + private child epg-list-item/ (libs/ui/epg)
• EpgViewComponent and LiveEpgPanelComponent (libs/ui/shared-portals)
• StalkerCollectionChannelsListComponent (libs/portal/stalker/feature)
• NavigationComponent (libs/portal/shared/ui — sibling portal-rail-links.component kept)
• FilterSortMenuComponent (libs/playlist/shared/ui)
• video-player ToolbarComponent (libs/ui/playback — sibling sidebar/ kept)
• PortalCollectionShellComponent (libs/portal/shared/ui)
• LoadingOverlayComponent (libs/portal/xtream/feature)

Alive code extracted from the deleted trees

• LiveEpgPanelSummary interface → libs/ui/shared-portals/src/lib/live-epg-panel-summary.ts (4 live layouts import it via the barrel, unchanged)
• EpgProgramActivationEvent interface → libs/ui/epg/src/lib/epg-program-activation-event.ts (used by the timeline and 3 layouts)
• epg-list.utils.ts trimmed to the three helpers the EPG timeline still uses (getProgramTimeMs, getProgramDateKey, areProgramsSame) and moved to libs/ui/epg/src/lib/epg-program.utils.ts
• epg-item-description/ moved up out of the deleted epg-list/ folder (still used by the programme dialog, multi-EPG, and channel-list-item)

Cleanup

• 18 orphaned i18n keys removed from all 18 locales (checked for dynamic key construction before removing)
• Dead CSS selectors removed from styles.scss, _portal-layout.scss, unified-live-tab.component.scss
• Unused deps removed: lodash (+ @types/lodash), semver, @ngrx/component-store, @videojs/http-streaming (videojs-quality-selector-hls declares no peer dependency on it; video.js 8 bundles VHS internally)
• Docs updated: docs/architecture/m3u-playlist-module.md, docs/architecture/iptvnator-ui-guidelines.md, CLAUDE.md

Testing

• pnpm nx build web — passes
• pnpm nx build electron-backend — passes
• pnpm nx affected -t test --uncommitted — 113 tests across 34 projects, all pass
• pnpm nx affected -t lint --uncommitted — 38/40 pass; the 2 failures (workspace-shell-util, remote-control) are pre-existing issues in files this PR does not touch
• No new regression tests: pure dead-code removal with no behavior change; deleted specs belonged to the deleted components

Greptile Summary

This PR removes nine verified-dead Angular components (~4,800 LOC) left over from the EPG timeline rework in #1102, along with orphaned i18n keys, dead CSS selectors, and four unused npm dependencies. The alive code embedded in those trees (two interfaces and a utility module) has been cleanly extracted into standalone files.

• Components deleted: EpgListComponent, EpgViewComponent, LiveEpgPanelComponent, StalkerCollectionChannelsListComponent, NavigationComponent, FilterSortMenuComponent, video-player ToolbarComponent, PortalCollectionShellComponent, and LoadingOverlayComponent — each verified to have zero class references and zero selector usages outside their own files.
• Alive code extracted: LiveEpgPanelSummary and EpgProgramActivationEvent interfaces promoted to standalone files; utility helpers from epg-list.utils.ts retained in a new epg-program.utils.ts; epg-item-description/ moved up to libs/ui/epg/src/lib/.
• Dependencies removed: lodash/@types/lodash, semver, @ngrx/component-store, and @videojs/http-streaming from package.json; no remaining imports found for any of them.

Confidence Score: 5/5

Safe to merge — pure dead-code removal with all alive code correctly extracted and re-wired.

Every deleted component was verified to have zero class references and zero selector usages in the surviving codebase. All import paths for the relocated utilities and interfaces were updated across eight consumer files. The barrel exports for both affected libraries are consistent with what the surviving callers import. Removed npm packages have no remaining import sites. The build and 113 unit tests pass per the PR description.

No files require special attention. The extracted utility file (epg-program.utils.ts) and the two new interface files are straightforward and match their consumers exactly.

Important Files Changed

Filename	Overview
libs/ui/epg/src/lib/epg-program.utils.ts	New utility file extracted from the deleted epg-list.utils.ts; contains getProgramTimeMs, getProgramDateKey, deduplicateProgramsByTimeSlot, and areProgramsSame — all still referenced by surviving consumers.
libs/ui/epg/src/lib/epg-program-activation-event.ts	Interface extracted from the deleted EpgListComponent; now has its own file and barrel export, used by the timeline and list-view components.
libs/ui/shared-portals/src/lib/live-epg-panel-summary.ts	LiveEpgPanelSummary interface extracted from the deleted LiveEpgPanelComponent; the barrel now only exports this interface, matching all four import sites.
libs/ui/epg/src/index.ts	Barrel updated: removed epg-list and epg-list/epg-item-description exports; added epg-item-description (from moved location) and epg-program-activation-event exports.
libs/ui/shared-portals/src/index.ts	Barrel now exports only the LiveEpgPanelSummary interface; epg-view and live-epg-panel component exports removed along with their deleted components.
package.json	Removes four unused direct dependencies: lodash/types, semver, @ngrx/component-store, and @videojs/http-streaming; no remaining imports found for any of them in the codebase.
tools/coverage/coverage-policy.json	Moves shared-portals from the covered section to the excluded section with an accurate reason (now a type-only library with no runtime code to test).
apps/web/src/assets/i18n/en.json	18 orphaned i18n keys removed; verified no remaining references in templates or TypeScript files across the repo.
libs/ui/styles/_portal-layout.scss	Dead CSS selectors targeting app-live-epg-panel and app-epg-view removed; surviving selectors for app-epg-timeline and app-epg-list-view retained.
