[management,client] Add anonymize level and upload URL to remote debug bundle jobs (#7147)

This extends the management-requested remote debug-bundle job with two
new, optional parameters. anonymize_level selects how aggressively the
bundle is scrubbed: "default" keeps internal (private) IP ranges
readable, while "strict" also anonymizes private, CGNAT and link-local
addresses; the value is trimmed and lowercased, and an unknown level is
rejected at creation. upload_url lets an operator point the peer at a
specific upload service instead of the default one; it must be a
well-formed https URL with a host, and an empty value falls back to the
default upload server. Both fields flow through the job workload API and
are surfaced in the create-debug-job modal on the dashboard. Validation
is shared so the client executor and the management boundary agree on
what a valid upload URL is, preventing drift between the two checks.
