scp81: PSK TLS server and command scripting (phases B/C) + BIP fix (v2.1.5)

- scp81.py: PSK TLS listener (stdlib ssl PSK callbacks) speaking the GP
  HTTP administration dialog; configurable framing (chunked/Content-Length,
  TLS record split, Apache-style/compact headers, Connection header,
  keep-alive, Next-URI template with %d, TLS version/cipher, answer delay,
  keylog for capture decryption)
- server.py: script responder + Response Scripting parsing (AF/AB, 80/23
  TLVs), memory decoder, SCP81 start options, terminal-side timer
  management, background-mode BIP events, permissive OPEN CHANNEL
- BIP fix: the RECEIVE DATA channel-data TLV length is BER long form
  (36 81 <len>) above 127 bytes; a raw length byte is mis-parsed on the
  card, so the large TLS records never reached its stack (a live card
  fetched the script response and silently never processed it - endless
  resume). The card now executes scripts and returns R-APDUs: memory
  (13 applets, 50646 B NV free, 2402 B volatile), ISD, stored HTTP OTA
  parameters, ELF and application registries
- frontend: SCP81 tab (listener, script selection, HTTP OTA log), phone
  event forms, i18n; service worker v141
- docs: api.md, scp81-findings.md (attempt matrix + root cause analysis);
  tools/scp81_decrypt.py decrypts listener captures via the keylog
- tests: 187 python + 337 frontend
