docs(audiobookshelf): the first run is a script, and its re-run is the scan trigger

The page claimed the account can only be created from a LAN address; measured,
the door is POST /init and it answers plain text. Replaced with the bootstrap the
deployer now runs, and with the doors a consumer actually needs: /status reports
isInit with no /api prefix, the item count rides /api/libraries/{id}/items ->
total (the library DTO has no totals), and the list DTO carries media.numTracks
while /api/items/{id} returns media.audioFiles.

New law: the folder watcher cannot cross the rootless podman bind — the same gap
as Jellyfin's auto-scan note — so files added on the host stay invisible until a
scan runs, and the deployer's re-run of the bootstrapper is the cheap trigger.

Testing Policy lists the new seam; index.md regenerated from frontmatter.
