* feat(library): local lossless index, filters, and conserve dedicated page

Add SQLite-backed lossless album browse and advanced-search filtering,
wire All Albums and artist/album lossless drill-down mode, and hide the
standalone /lossless-albums nav entry from sidebar visibility settings
(conserved route, default off).
