net-sim: network-condition simulation in the Phone tab (v2.5.0)

Browse Source 
Server (pysim_simple_server/netsim.py + POST /api/net-sim):
- pure builders for the observed phone write vocabulary (UICC_NAA.md §13):
  EPSNSC (A0 TLV with KSI/KASME/counts/algo, padded to the card's FCP record
  size; invalidate-wipe and invalidate-keep-key), LOCI/PSLOCI/EPSLOCI real
  and dummy forms (PLMN kept, LAC FFFE, status 01/02), Kc/KcGPRS (9-byte
  USIM and 33-byte GSM forms, 07 invalidates), EF.SMSstatus counter bump
  (read-modify-write), CBMI/CBMIR, the Location status event (9B 01 <st>,
  with the optional 13 07 location info for normal service) and the
  AUTHENTICATE APDU (TS 31.102 7.1.2.1) with DB/DC response parsing
- scenario runner executes the recipes under _CARD_LOCK, picks the first
  existing candidate path (ADF.USIM vs DF.GSM/DF.TELECOM), reads FCP/current
  records where the format is card-specific, skips the event unless the card
  subscribed to Location status, honours the scenario toggles and returns a
  per-step log; only D6/DC, ENVELOPE and AUTHENTICATE are ever sent
- GET /api/mcc-mnc serves the optional worldwide operator list
  (--mcc-mnc-list, default <workspace>/samples/mcc-mnc-list.json): ?q=
  search and ?random=1&exclude= for roaming; the list stays out of the repo

PWA:
- Phone pill gains a 'Network simulation' fieldset: one button per scenario
  (cold boot, EPS/2G attach, service lost, limited service, roaming denied,
  churn, SMS received, CB reconfig, AUTHENTICATE), a collapsed Parameters
  block (operator search + random roaming, LAC/Cell ID/TAC/RAC, optional
  identities, toggles, churn count/delay) and a step log with SWs
- i18n EN/RU, help/README/api.md/AGENTS.md updated; version 2.5.0,
  SW cache simple-v193

Tests: tests/test_netsim.py (19), frontend/tests/netsim.test.js (3) and
html guards - 423 frontend / 280 Python, all passing

Values persist on the server until restart. Apply → hex updates; Save → POSTs to server. The server will use these values to populate TERMINAL RESPONSE data for future PLI proactive commands.
**Network simulation** — replays the card-facing write patterns of a real phone on network-condition changes (trace study: `projects/UICC_NAA.md`): **Cold boot**, **EPS attach**, **2G attach**, **Service lost**, **Limited service**, **Roaming denied**, **Churn**, **SMS received**, **CB reconfig** and **AUTHENTICATE**. Each scenario sends the Location status event (only when the card subscribed to it), updates the EPS NAS context, location files, Kc and CB/SMS files exactly as observed, and logs every step with its SW. Parameters (collapsed) cover the operator (searchable worldwide MCC/MNC list served by the server, plus a random roaming picker), LAC/Cell ID/TAC/RAC, optional identity values (empty = random: TMSI, GUTI, KSI, KASME, Kc, NAS counts, algorithm, RAND/AUTN), scenario toggles and the churn count/delay. Only UPDATE BINARY/RECORD, ENVELOPE and AUTHENTICATE are sent; FPLMN and 5GS location files are never touched. The operator list comes from `--mcc-mnc-list` (default `<workspace>/samples/mcc-mnc-list.json`).
