ScanPodcastFolder walks a podcasts-typed media folder, treating each
subdirectory as a podcast show and each audio file inside as an
episode. Writes media_items.type='podcast' + episodes rows + media_files
rows. RSS-subscribed feeds (podcast_feeds table) arrive in sub-plan 5;
this task covers filesystem-only ingestion.
ScanFolder dispatches to this path when folder.Type='podcasts'.

Folders containing N audio files (one per chapter/part) get one
parsedAudiobookFile per file; each file's chapter list is synthesized
as a single chapter with title = filename stem. Title/author/series/
year come from the first file's tags.
Also drops the duplicate pickFirstNonEmpty helper added in Task 6 in
favor of the existing firstNonEmpty already in probe.go.

The audiobook scanner needs format-level tags (title, artist, album,
date) for media_items metadata; ffprobe already parses them in
ffprobeFormat.Tags but ProbeData previously discarded them. Add
FormatTags map[string]string to ProbeData, populate it in
convertProbeData via a new normalizeFormatTags helper that lowercases
keys and trims values.
Adds a fixture audiobook .m4b with embedded chapters (Intro/Outro) and
format tags, and a test that verifies ProbeFile() returns both
correctly.
