feat(rawcli): annotate read/write output with datasheet memory regions

A READ now names the memory locations the pages cover, per the tag's datasheet layout,
grouping consecutive same-role pages:

  READ(0)  -> 00-02 → UID / serial number  ·  03 → Capability Container (CC)
  READ(4)  -> 04-07 → user memory
  READ(0xE3) -> E3 → CFG0 · E4 → CFG1 · E5 → PWD · E6 → PACK

TagCommand gains a pages() callable (which page/block numbers a command touches: READ = 4
pages from <page>, FAST_READ = <start>..<end>, WRITE = one page). memory.region_annotation()
groups those into "lo-hi → role" via the existing page_role layouts; _handle_call prints it
after the exchange. No layout for the tag (e.g. MIFARE Classic) -> no annotation.

Hardware-verified on NTAG216 (READ 0/4/0xE3, FAST_READ). Tests for the grouping + the
dispatch path. 1264 green.
