fix(messaging-ui): unreadable code chip on own messages + raw markers in previews

Two bugs from the formatting work, both visible in the CRM messenger:

1. Inline code / code blocks were invisible in your OWN bubbles. `.miu-code` sets
   background: --miu-panel-2 (#1d1d26) while the is-mine override set only the
   colour to --miu-accent-text (#1a1206) — near-black on near-black, ~1.03:1
   contrast. The chip now tints the accent bubble (rgba(0,0,0,.16)) instead of
   using the panel colour, so it reads against any accent.

2. The conversation list showed the raw last message, so a strikethrough message
   previewed as "~crazy~". Adds stripMarkup() — markers off, code unwrapped,
   nesting handled, honouring the same word-boundary rule so snake_case_name and
   "5 * 3" survive — and uses it for the preview line.

Bumped to 0.1.10. SDK suite: 17 files / 98 tests green.
