RAM constructor fixes: EA/CA nesting, access domain order, menu pairs, BER lengths, services byte (TS 102 226)

- UICC Toolkit tag 80 nested inside EA (EA 12 80 10 ...)
- ram-tk-mode value ea (was 80), label 'UICC Toolkit (Tag EA)'
- SIM (CA) access domain FIRST in payload, blank = 00
- Menu entries: 2×m pairs (i=1 first, i=m last, else 0000)
- CA/EA lengths via berLenStr() (supports 81xx long form)
- UICC trailing 'Maximum number of services' byte (ram-tk-services)
- DELETE: P1=00 fixed, mode in P2 (80E4 00 <mode> ...)
- STORE DATA: ram-enc 00/40/80/C0/E0 with correct labels
- LOAD: P1 fixed to 0x80 (last block)
- USIM SELECT: selP1 0x09 -> 0x00 (select by file id)
- ram.test.js: 11 exact-hex tests from exchange vectors
- v1.8.1, SW cache otaman-v9
