scp81: RAM install over HTTP OTA (v2.1.8)

- shared _cap_apdu_sequence helper (INSTALL [for load] -> 240-byte LOAD
  blocks -> INSTALL [for install]); the SCP80 /api/ram-install path now uses
  it too (one source of truth; byte-level tests pin the APDUs)
- POST /api/scp81/ram-install: parses the .cap server-side and queues the
  APDU sequence as the SCP81 command script (one C-APDU per POST, runs on the
  card's next push); refused while a script is mid-run unless force
- /api/scp81/script reports the script kind (explore/none/custom/ram-install)
- tab: RAM install row (CAP file + SD AID + Queue button); RU strings
- docs: api.md, findings, AGENTS; service worker v145
