Decode SET UP IDLE MODE TEXT command data; bump to 1.11.0

TS 102 223 §6.6.13 support for the SET UP IDLE MODE TEXT (0x28)
proactive command:

- Command qualifier: COMMAND_QUALIFIERS entries may now be callables
  for bitmask-style qualifiers; _idle_text_qualifier decodes bit 1
  as "icon self-explanatory", hides 0x00, falls back to raw hex on
  RFU bits.
- Icon Identifier TLV (0x1E) parsed into icon_id (image record
  number in EF_IMG, 0 = none); rendered as an "Icon" detail row in
  the PWA.
- Zero-length Text String TLV now yields text='' ("remove idle mode
  text") instead of being silently skipped.

Tests: +6 TestIdleModeText cases (8-bit/UCS-2 text, icon TLV,
qualifier variants, empty text) — 285 total. SW cache bumped to
simtrace-analyser-v14.
