Implement all remaining PlayerApiClient stubs and add unit tests

Implements every previously-unimplemented method in DioPlayerApiClient:
shares (listSharesForMedia, listMyShares, revokeShare), public shared-media
endpoints (getSharedMediaPage, streamSharedMedia, getSharedThumbnail,
downloadSharedMedia), config (getConfig), sets (getSetCover, updateSetCover,
uploadToSet), media helpers (regenerateThumbnail, deleteMedia, restoreMedia),
progress batch (batchUpdateProgress), podcasts (listPodcasts, listEpisodes,
downloadEpisode, toggleEpisodeComplete), admin users/permissions/scanner
(listUsers, createUser, deleteUser, listPermissions, grantPermission,
revokePermission, triggerRescan, getScanProgress, listTrash), and API tokens
(listAPITokens, createAPIToken, revokeAPIToken).

Adds listAPITokens/createAPIToken/revokeAPIToken/batchUpdateProgress to the
abstract PlayerApiClient.  Corrects listPermissions return type from
List<Map> to Map<String,dynamic> to match the server's single-object response.

Adds 18 new unit tests covering shares (listMyShares success/empty/401,
revokeShare success/404/401) and podcasts (listEpisodes success/pagination/
empty/401, toggleEpisodeComplete success/404/401).  All 264 tests pass.
