Fix podcast support critical bugs from code review

- Fix boolean scanning from SQLite INTEGER columns (intToBool helper)
- Fix BrowseSet LIMIT 0 returning zero episodes (use 1000 instead)
- Fix checkFeed double-fetch by parsing from resp.Body directly
  + Add ParseFeedReader for body reuse
- Fix file handle leak in DownloadEpisode (explicit Close before ImportMediaFile)
- Fix incomplete rollback in DownloadEpisode (remove file + delete media row)
- Fix 204 No Content handler writing 'null' body
- Fix DownloadCoverImage to accept *http.Client with timeout
- Deduplicate uniqueFilename into shared internal/service/filename.go
- Wire frontend renderPodcastEpisodes into renderBrowse from API data
- Refactor podcasts.js: remove extra API call, fix toggle toast, remove duplicate toast
- Add Config.PodcastCheckMinutes + PODCAST_CHECK_INTERVAL_MINUTES env var
- Start background CheckFeeds goroutine in main.go with ticker
- Update NewPodcastService to accept checkInterval parameter
- Log errors from CheckFeeds and episode creation instead of silently discarding
