* feat(relay): log metrics and alerts for fenced and fatal rejections and the lease shadow

orca_relay_database_rejection_fenced and orca_relay_process_fatal become
incident counters on directors and cells, each with an alert at the first
event. The lease shadow line gets one distribution metric per class plus
the hello database read p99, and an alert when bad signatures persist on
a cell for 15 minutes.

* fix(relay): one fleet-wide fenced-rejection alert, director-only fatal page, console-only bad-signature alert

A database fault reaches every process at once, so fenced rejections sum
into one series. Cells' fatal rejections already page through the cell
exit alert, so the fatal page covers directors only. The bad-signature
alert can be held up by one client, so it stays in the console.

* fix(relay): fleet-wide fenced-rejection alert as one PromQL sum, like the fix-level alert

* feat(relay): metric for the lease shadow's database-refused count
