feat(rawcli): live relevance hint — per-transponder memory map

Surfaces what the input *means* on the identified tag, in a bottom-bar
hint that updates as you type (the point, over aggressive autocomplete):

- memory.py: page_role(transponder, page) maps a page/block to its role
  on the specific IC — UID, Capability Container, user memory, dynamic
  lock, CFG0/AUTH0, CFG1/ACCESS, PWD, PACK. Layouts mirror the models'
  page attributes (NTAG210/212/213/215/216, Ultralight EV1); a test
  guards against drift.
- input_hint(session, text): the command's purpose, and — once a page
  argument is typed (even partial, hex or decimal) — where that page
  lives. e.g. "READ(4)" -> user memory, "READ(0x2B" -> PWD,
  "WRITE(0x29" -> CFG0/AUTH0.
- app: wired as the prompt's bottom_toolbar.
