Andrei Kvapil 851a86dcf1 feat(platform): orphan tenant FluxCD HelmReleases on upgrade
Add migration 54 for the removed addons.fluxcd feature. For every tenant
that had it enabled, the FluxCD HelmReleases in the management cluster
are suspended, stripped of their Flux finalizer and deleted, so the
delete does not trigger a Helm uninstall inside the tenant cluster. The
Flux release already running in the tenant keeps running untouched.

Runs as a pre-upgrade hook, before the addon-less Kubernetes chart
reaches the tenant HelmReleases. Mirrors the orphan idiom of migration
29. Bumps migrations.targetVersion to 55.

Fail closed. Dropping the finalizer is the only thing that keeps the
delete inert, and migrations never re-run, so the script runs under
`set -euo pipefail` with no `|| true` on the critical path and gates the
delete on the finalizer actually being gone. The verify read uses
`--ignore-not-found` rather than `2>/dev/null || true`, so a failed read
aborts instead of reading as an empty finalizer list that passes the
gate on an object whose state was never checked. A migration that stops
is recoverable; one that half-orphans a fleet is not.

Cover it with a docker + fake-kubectl unit test running the real script
by path inside the migrations image's own alpine base (busybox ash, jq
baked on), so it exercises the shipped interpreter and load-bearing
pipefail. The suite pins ordering and selection (only the addon
HelmReleases are touched, each suspend -> finalizer-drop -> delete in
order) and the fail-closed paths (a surviving finalizer, a failing
verify read, and a failing fleet scan each abort before deleting and
before stamping).
