fix(reticulum): CodeRabbit a11y and listener-off retry toast

[rinchen]

Summary

• Follow-up to fix(reticulum): block RNCP sends to unreachable receive dests #747 CodeRabbit notes: darker Remote pending-offer badge (bg-amber-800), capped 99+ aria label, axe coverage for badge/banner.
• Distinct toast when retry hits listenerLikelyOff without opening the enable-request modal.

Test plan

• Remote sidebar badge shows amber-800 styling and passes axe with pending offers.
• Badge/aria show 99+ when pending offers exceed 99.
• Chat DM offer banner Accept/Reject has no axe violations.
• Retry of a failed transfer with listenerLikelyOff toasts the listener-off message (not peer offline).

Summary by CodeRabbit

• Bug Fixes

  • Retry attempts now show a clear error when the receiving destination is unreachable, without opening an unnecessary dialog.
  • Remote pending-offer counts display correctly, including a capped “99+” indicator and clearer labeling.
  • Remote transfer requests now include readable instructions and destination details across compatible messaging apps.

• Accessibility

  • Improved accessibility support for Remote offer badges and transfer banners.

Warning

Review limit reached

@rinchen, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 5 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
