feat(DiscoveryMountain): add download progress overlay and per-episode resume tracking

Browse Source

- Show full-screen downloading modal with progress bar, percent and KB detail, cancel button
- Track dl_total/dl_expected without LVGL locks, update via ui_timer (200ms)
- Normalize audio URLs (relative /api/files/ -> PB prefix), grow PSRAM fetch buffer 64K->600K, handle timeouts and require 95% of Content-Length
- Persist per-episode playback position in state.json positions map, restore on select_ep/go_next/go_prev
- Save position periodically (5s), on pause, on hide, and on natural finish (clears completed)
- Fix seek on resume using byte estimate and total_decoded_samples correction
- Verified symbols: 111 undefined, all exported
