Default to disabled state, add library-level bulk toggles, and make Sync/Share header copy tab-aware

[Copilot]

• Resolve main.ts conflict block 1: merge updateTopDescription into setActiveTab; drop isShareTabContext
• Resolve main.ts conflict block 2: keep setActiveTab(activeTab) in mountPage; remove orphaned listener setup
• Add independent share state variables (shareDisabledSeriesIds, shareDisabledSeasonIds, etc.)
• Add tab-aware state accessors; update all card and library-toggle functions to use them
• Sync defaults to all-enabled (from config); Share always defaults to all-disabled on page mount (once per init(), not per search)
• Update share() to use share-specific state sets
• Reset share state in mountPage on navigation
• ShareController.cs: remove redundant field; use primary constructor param directly
• ShareSubmitRequest.cs: IReadOnlyCollection + [JsonInclude] + init; for true immutability
• ShareSubmitResponse.cs: use init; instead of set; with corrected doc comments
• SegmentStore.cs: add Id INTEGER PRIMARY KEY to SharedUploads + migration for existing DBs
• ShareSubmissionService.cs: fix full-library scan (AncestorIds); fix partial-success race condition (record fingerprints immediately per-batch); ok flag starts false and is set true only when a batch actually succeeds
• Build passes clean (0 errors, 0 warnings); tests pass
• Parallel validation passed (0 CodeQL alerts)
