Felix Wolf 137705bfe0 feat(matrix): add Synapse + Element Web deployment
Personal homeserver with bridges deferred. Single host
matrix.{cluster.domain} with path-based routing: /_matrix, /_synapse,
/.well-known/matrix → Synapse; / → Element Web. Both share matrix-tls.

Stack: ananace/matrix-synapse + element-web charts, CNPG postgres
(LC_COLLATE=C), in-cluster alpine redis (no auth, replaces bitnami
subchart), mittwald-generated synapse-secrets for registration_shared/
macaroon/form_secret, custom idempotent signing-key init Job (replaces
chart's bitnami/kubectl publisher).

Sync waves:
  -3 Namespace
  -2 synapse-secrets (mittwald head-start), signing-key RBAC
  -1 signing-key Job, CNPG Cluster, redis
   0 Synapse, Element, Ingress

Synapse pod waits in extraCommands until synapse-secrets is populated,
then writes zz-overrides.yaml to override chart placeholders for the
three secret values without churning the chart-managed Secret on every
render. Resources tightened for 1-2 user scale: Synapse 256Mi/512Mi,
Postgres 64Mi/128Mi.

ArgoCD destination.namespace overridden to matrix via prototype-level
argocd overlay so both apps share the matrix ns instead of creating
unused matrix-synapse and element-web namespaces.
