fix(vms): revert UniFi cloud-init to minimal inline userData (1112B)

userDataSecretRef tripped a Flux server-side-apply schema quirk on the KubeVirt
VirtualMachine CRD ("field not declared in schema"). Go back to inline userData,
trimmed to 1112 bytes (< the 2048 limit) by dropping the break-glass SSH key —
no longer needed for debugging now that the postBuild cloud-init corruption is
fixed. Keeps qemu-guest-agent (AgentConnected proves cloud-init ran) and the
public-API UOS resolver + non-interactive install. Removes the secretGenerator +
unifi-cloudinit.yaml. (Add SSH back via userDataSecretRef only if the SSA quirk is
worked around and guest access is needed.)

#cloud-config
# UniFi OS Server VM cloud-init. Wrapped into a Secret (userDataSecretRef) by the kustomization's
# secretGenerator because it exceeds KubeVirt's 2048-byte inline cloudInitNoCloud.userData limit.
# NON-SENSITIVE (a public SSH key + a public installer script), so it is NOT SOPS-encrypted.
#
# install-uos resolves the LATEST UniFi OS Server linux-x64 installer from Ubiquiti's PUBLIC firmware
# API (fw-update.ui.com/api/firmware-latest, no auth) — no per-release URL to bump (override with
# UOS_URL=<href>). cloud-init installs the prerequisites, downloads the installer (~840MB) and runs it
# NON-INTERACTIVELY (`yes |`). The UI comes up on https://<vip>:11443 once installed.

# Break-glass OS access on the default `ubuntu` user (public key — safe to commit) for ops/debugging.
# qemu-guest-agent (below) additionally enables `virtctl` guest access.
