feat(seer): Show project platform icon next to short ID on overview card (#122232)

Add a project platform icon (`ProjectAvatar`) beside the group short ID
on the Seer autofix overview card.

The card rendered the short ID as bare monospace text, unlike nearly
every other short-ID surface in the app — issue stream rows, the
issue-detail header, and the event drawers all already show a project
graphic next to the short ID. This brings the overview card in line so
each card indicates at a glance which project/platform the issue belongs
to.

The project (including `platform`) is already present on the card's run
data, so no data threading or API changes were needed. The avatar falls
back to a generic icon when `platform` is absent, and the project slug
shows on hover.

Scope is intentionally limited to this card; the remaining bare short-ID
sites (autofix markdown embed, Discover/dashboards field renderers) are
left for a follow-up.
