feat: card-driven STATUS polling and the Poll Interval Negotiation event (v3.5.9)

- EVENT_NAMES (server + PWA) corrected against TS 102 223 v18.3.0 8.25:
  0x14 is "Access technology change (multiple)" (not Change of UICC
  Access), 0x19 Profile container, 0x1A Void, 0x1B Secured profile
  container, 0x1C Poll interval negotiation, 0x20-0x22 reserved.  Values
  the CAT spec leaves "Reserved for 3GPP" now carry the concrete TS 31.111
  event name + clause (0x11 (I-)WLAN access status, 0x12 Network
  rejection, 0x15 CSG cell selection, 0x17 IMS registration, 0x18 Incoming
  IMS data, 0x1D Data connection status change, 0x1E CAG cell selection,
  0x1F Slices status change).
- Poll Interval Negotiation (0x1C) in the Phone tab: the form proposes a
  Duration (unit + interval) and the UICC's answer (TS 102 223 8.97
  accepted / rejected / modified + optional Duration) is decoded and
  shown; a "modified" duration becomes the background poll interval.  The
  form appears when the card subscribed to the event, like every other.
- Polling emulation is card-driven: a POLL INTERVAL adopts its Duration
  (minutes/seconds/tenths -> 1..255 s, logged) for the background poll,
  is echoed in the TERMINAL RESPONSE (6.8.4) and clears a POLLING OFF
  suspension; POLLING OFF (6.4.14) suspends proactive polling until a new
  POLL INTERVAL - the manual Send STATUS button and presence detection are
  unaffected.  /api/poll-status and /api/poll-toggle report card_disabled
  (+ a warning when enabling while suspended); the PWA shows it in amber.
- Tests: tests/test_poll.py +7, test_proactive_names.py +3, frontend
  event_forms +2 and poll_ui (4).  Help EN/RU, docs/api.md, AGENTS.
