fix: decouple at-rest encryption from JWT_SECRET, add JWT rotation
Introduces a dedicated ENCRYPTION_KEY for encrypting stored secrets
(API keys, MFA TOTP, SMTP password, OIDC client secret) so that
rotating the JWT signing secret no longer invalidates encrypted data,
and a compromised JWT_SECRET no longer exposes stored credentials.
- server/src/config.ts: add ENCRYPTION_KEY (auto-generated to
data/.encryption_key if not set, same pattern as JWT_SECRET);
switch JWT_SECRET to `export let` so updateJwtSecret() keeps the
CJS module binding live for all importers without restart
- apiKeyCrypto.ts, mfaCrypto.ts: derive encryption keys from
ENCRYPTION_KEY instead of JWT_SECRET
- admin POST /rotate-jwt-secret: generates a new 32-byte hex secret,
persists it to data/.jwt_secret, updates the live in-process binding
via updateJwtSecret(), and writes an audit log entry
- Admin panel (Settings → Danger Zone): "Rotate JWT Secret" button
with a confirmation modal warning that all sessions will be
invalidated; on success the acting admin is logged out immediately
- docker-compose.yml, .env.example, README, Helm chart (values.yaml,
secret.yaml, deployment.yaml, NOTES.txt, README): document
ENCRYPTION_KEY and its upgrade migration path

1. Secret handling (JWT_SECRET and ENCRYPTION_KEY):
- By default, the chart creates a Kubernetes Secret from the values in `secretEnv.JWT_SECRET` and `secretEnv.ENCRYPTION_KEY`.
- To generate random values for both at install (preserved across upgrades), set `generateJwtSecret: true`.
- To use an existing Kubernetes secret, set `existingSecret` to the secret name. The secret must contain a key matching `existingSecretKey` (defaults to `JWT_SECRET`) and optionally an `ENCRYPTION_KEY` key. If `ENCRYPTION_KEY` is absent from the external secret, the server auto-generates and persists it to the data volume.

2. ENCRYPTION_KEY notes:
- Encrypts stored API keys, MFA secrets, SMTP password, and OIDC client secret at rest.
- If left empty, auto-generated by the server and saved to the data PVC — safe as long as the PVC persists.
- Upgrading from a version that used JWT_SECRET for encryption: set `secretEnv.ENCRYPTION_KEY` to your old JWT_SECRET value to keep existing encrypted data readable, then re-save credentials via the admin panel.
3. Example usage:
- Set explicit secrets: `--set secretEnv.JWT_SECRET=your_secret --set secretEnv.ENCRYPTION_KEY=your_enc_key`
- Generate random secrets: `--set generateJwtSecret=true`

- Use an existing secret: `--set existingSecret=my-k8s-secret`

4. Only one method should be used at a time. If both `generateJwtSecret` and `existingSecret` are set, `existingSecret` takes precedence.
If using `existingSecret`, ensure the referenced secret and keys exist in the target namespace.
