fix: embed images inline in Gitea issues, fix retry dropping attachments (v0.51.6)

Two related bugs in the Gitea issue body:

1. Attachments were always plain bullet links (`- url`), even for images —
   so they never rendered as a preview in the Gitea issue, just a clickable
   URL. Image content-types now use markdown image embed (`![](url)`).
2. The admin "Create Gitea issue" retry action built its own body from
   scratch (`ticket.description` only) and never queried attachments at
   all — a retry always lost them, regardless of point 1's fix.

Extracted buildGiteaIssueBody() to lib/gitea.ts so both the initial
ticket-creation path and the retry path share one body-building
implementation instead of two independent (and inevitably diverging) ones.
