store: add NoPayStation source (PSP + PS1 Classics .pkg)

New 'NoPayStation' option in the Store tab lists PSP_GAMES.tsv and
PSX_GAMES.tsv, downloads each item's encrypted .pkg and decrypts/extracts
it with pkg2zip into a configurable output dir (<dir>/PSP/<TITLE_ID>/ and
<dir>/PSX/<TITLE_ID>/). Downloaded PSP games and PS1 Classics appear in the
Library (games/eboot and ps1/eboot respectively) and copy to the PSP as
PSP/GAME folders.

- app/nopaystation.py: TSV fetch/parse (cached) + pkg2zip discovery/extract.
- app/transfers.py: NoPayStationSource (scan + download).
- Settings: NPS output dir + pkg2zip path (QSettings nps_dir/pkg2zip_path).
- StorePage: NPS source + content-type combo (PSP Games / PS1 Classics),
  per-item cover system, TSV release dates, nps-download job kind.
- Library: _nps_library_items ingest, on-PSP detection, folder copy/delete,
  PPSSPP play disabled for encrypted PSP EBOOTs.
- README: document the source, pkg2zip + npdrm_free requirements.

+### 4. NoPayStation
+
+The **NoPayStation** source lists PSN content from
+[NoPayStation](https://nopaystation.com/) — **PSP games** (`PSP_GAMES.tsv`) and
+**PS1 Classics** (`PSX_GAMES.tsv`), selectable from the content-type dropdown
+next to the source selector.
+
+Requirements & behaviour:
+
+1. Install [`pkg2zip`](https://github.com/mmozeiko/pkg2zip) (the same tool the
+   pkgi family uses) and either put it on `PATH` or set its path in
+   **Settings → Store**. NoPayStation `.pkg` files are encrypted PSN packages,
+   not ZIPs — `pkg2zip` decrypts them.
+2. Set **NoPayStation output dir** in **Settings → Store** (default
+   `$PSP_STATE_DIR/nps`).
+3. Downloading a PSP game writes `PSP/<TITLE_ID>/EBOOT.PBP`; a PS1 Classic
+   writes `PSX/<TITLE_ID>/EBOOT.PBP`. Both then show up in the **Library**
+   (PS1 Classics under **PS1**, PSP games under **Games**) and can be copied to
+   the PSP like any other item.
+4. The TSV lists are cached in the state dir and refreshed on each store scan.
+
+> **DRM note:** NPS content is PSN-DRM'd. To *run* it on the PSP you need the
+> [`npdrm_free`](https://github.com/qwikrazor87/npdrm_free) plugin (ARK and most
+> CFW already ship it). The desktop app only downloads and decrypts; it doesn't
+> strip DRM.
