feat: blame page revamp + blob/blame perf fixes

- Blame page full redesign: new .blm-* CSS, symbol cards with colored borders, expandable history panels, file-level blame with line-annotated code view - ui_blame.py: fast path via symbol history index (O(1) vs O(N) snapshot scan), 50-commit cap on fallback scan, file content loading for file-level blame - ui_blob.py: load_symbol_history called once; _fetch_file_history uses index fast path with dedup; _fetch_file_symbols/intel accept pre-loaded history - musehub_repository.get_last_commit_for_file: index fast path - TDD: test_blame_page_perf, test_blob_page_perf, test_last_commit_index_lookup - blame.ts: replace MIDI tooltip with code blame hash navigation - SCSS: _blame.scss component + page partials, app.scss imports both
