Arsolitt 2ea4aad5de feat(redis): add operator-managed TLS via cert-manager PKI chain
Expose tls.enabled in the Redis chart values, mirroring the pattern
already in use by mariadb, nats, opensearch, qdrant and rabbitmq. The
flag is tri-state: when unset, TLS follows the value of `external`; an
explicit boolean overrides the default.

When TLS is enabled the chart renders the standard cozystack 4-resource
cert-manager chain in the release namespace:

  - Issuer (self-signed bootstrap)
  - Certificate (CA, ECDSA, isCA, rotationPolicy: Never, 5y)
  - Issuer (CA-backed)
  - Certificate (leaf, secret <release>-tls, ECDSA, 1y, rotationPolicy: Always)

The leaf certificate covers the SAN list the redis-operator computes for
its own Certificate (operator/redisfailover/service/generator.go:
redisCertificateDNSNames): short, namespace, .svc and .svc.<clusterDomain>
forms for rfr- / rfrm- / rfrs- / rfs- services plus a wildcard for
per-pod headless DNS names of the redis statefulset. Localhost is
included for in-pod readiness probes; when `external` is true the
tenant LB hostname is added too.

The chart hands the resulting Secret to the operator via
spec.tls.certificateSecret.secretName so the operator never creates a
duplicate Certificate; it just mounts the Secret into both Redis and
Sentinel pods and wires the redis tls-* directives. tls.authClients
maps to the Redis tls-auth-clients directive and defaults to "no".

The dashboard-resources Role is extended with the new TLS secret names
only when TLS is on, so the cozystack dashboard can read them to
display connection details.

Helm unit tests in tests/tls_test.yaml cover the tri-state resolution
(four enable/external combinations), SAN list coverage for all four
service names and the wildcard, custom cluster-domain handling, the
external SAN injection path, authClients propagation, and dashboard
RBAC expansion.

The comment above the CA usages named the wrong bits: cert-manager maps
signing to the digital signature bit, and crl sign and ocsp signing are
separate usages this chart does not request.
