feat(rawcli): finish T5577 catalog — page/password, RESET, hex data words

Round out the ATA5577C command set to the datasheet-catalog standard:

- RESET command (downlink opcode 00), backed by a new lf.t55.reset() that
  drives CMD_LF_T55XX_RESET_READ. Hardware-validated (status 0).
- READ/WRITE gain optional <page> (1 = traceability) and <password> for
  password-mode access, threaded through read_config / read_t55xx_block.
- WRITE data and all passwords now parse as hex words (like the pm3 client's
  -d/-p and every other rawcli WRITE); blocks/pages stay decimal. Previously
  T5577 WRITE data alone was base-10, so WRITE(0, 00088040) wrote decimal.

Live-validated on a T5577 emulating EM4100 00FFFFFFFF: DETECT/READ(0) decode
the config 00148040 (ASK/RF64/EM4100), RESET/WAKE return ok.
