Operations are now clickable from the host detail page, linking to
/ops/{id} which shows the operation info, host link, duration, and
activity log filtered to that operation. Active operations can be
cancelled, which transitions the host to failed and releases the lock.
SSE activity events now include operation_id for real-time filtering.

Hosts stuck in states like pxe_ready had zero visibility into why.
This adds a persistent activity log that records every meaningful
step (state transitions, PXE events, cluster join stages, failures)
and surfaces it on the host detail page with live SSE updates.
Includes a stuck-detection warning banner when a host sits in
pxe_ready for >10 minutes with no iPXE request.
