v3.25.2: the TR tag-form alignment with TS 102 223 6.8.0/6.8.1

The TR's response objects are all Min = N in the spec's own table, and
6.8.0 says such objects "should set the CR flag to comprehension not
required" - so the builders now emit the base tag forms:

- device identities 82 -> 02 (every builder)
- PLI data 93/94/AD/AE/BF/E2/E5 -> 13/14/2D/2E/3F/62/65 (26/63 already
  base); the PWA inline codecs follow
- POLL INTERVAL Duration 84 -> 04
- GET INKEY/INPUT Text string 8D -> 0D
- SELECT ITEM Item identifier 90 -> 10
- Timer identifier/value A4/A5 -> 24/25
(_bip_tr already used the reference traces' 01/02/03.)

The command details now echo the command's tag form (01/81) besides
its qualifier - 6.8.1 requires the object to be identical to the
command's "including the comprehension required flag": the parser
returns cd_tag and _build_tr, _handle_timer_command,
_handle_bip_command, the menu pendings and testscript.build_tr carry
it.  The Result keeps 03/83 (Min = Y).  _tr_data_only strips both tag
styles and the POLL Duration decode accepts 04.

Tests: the base forms per builder + the echo + the PWA drift guards;
883 frontend + 866 Python; sw cache simple-v426.
