feat(player-stats): local listening history tab with heatmap and summaries (#849)

* feat(player-stats): local listening history tab with heatmap and summaries

Record play sessions in library.sqlite when the library index is enabled,
add Rust read APIs and Tauri commands for year/day aggregates, and ship the
Player stats UI with session clustering, event-driven live refresh, and a
notice when some servers are excluded from indexing.

* test(player-stats): split play_session repo and expand test coverage

Move the repository into play_session/ (completion, cluster, integration tests),
add remap/purge/FK coverage in Rust, and cover ingestion gates plus live-refresh
hooks on the frontend per spec v0.3.

* docs(release): CHANGELOG and credits for player stats (PR #849)

* fix(player-stats): satisfy tsc and clippy CI gates

Use InternetRadioStation field names in the radio skip test and replace
manual month/day range checks with RangeInclusive::contains.
