feat: tabbed file lists with editable labels

Browse Source 
- Wrap the playlist in a QTabWidget; each tab is its own file list
- "+" corner button adds tabs; double-click a tab to rename inline; tabs are closable (last tab protected) and movable
- self._playlist now resolves to the active tab's PlaylistWidget
- Persist tabs (label + files + separators) per profile as JSON; falls back to legacy session_files/separators on first load
- Filter box and playlist filters apply to the active tab; tab switches reapply filters and refresh marks
- Profile switch/duplicate/delete now save/load/copy/remove per-profile tab state
