feat(DM): instant cache load, manual refresh, full-screen season selector, season persistence fix

- Cache loads synchronously on onShow for instant startup, no auto fetch
- Added manual Refresh button, removed auto refresh that blocked UI
- Made UI non-blocking during fetch (episode list usable while fetching)
- Fixed season loss after player/downloader by preserving season in static s_preserved_season surviving G memset
- Season selector now full-screen overlay parented to lv_scr_act()
- Removed DL Missing batch button and bottom help/status label per UX request
- load_state no longer overwrites browsing season with last_slug season
