v3.11.0: Cards tab redesign (list + editor), preset PIN/PUK codes

The Cards tab now shows the preset list by default; "Add preset" / "Edit"
open a separate editor view (Save stores and returns to the list, Cancel
discards; ramGoToPreset opens it too).  The editor keeps the name/ICCID
header (with From card) and groups its fields into bordered blocks:
- PIN/ADM: the new optional card codes PIN1/PUK1/PIN2/PUK2 (plain text,
  4-8 decimal digits) plus ADM, moved out of the top row; nothing consumes
  the PIN/PUK codes yet.
- TAR: one uniform table (TAR, MSL, description); the first three rows are
  the fixed role entries with the immutable English descriptions "ISD
  compact format" / "UICC shared FS RFM compact format" / "ADF FS RFM
  compact format"; further rows are deletable with an optional description.
- SCP80 (keyset editor) and SCP81 (PSK pair) as before.

Store: PRESET_FIELDS gains pin1/puk1/pin2/puk2 (optional; whitespace
stripped; 4-8 decimal digits validated on save and import), SCHEMA_VERSION
4, docs/help/AGENTS updated.  TAR rows use unified ids (cards-tr-N-*), the
editor switches via cardsShowList/cardsShowEditor.

Tests: 665 Python + 783 frontend green; the whole inline PWA script
syntax-checked.  sw cache simple-v361.
