Stanislas 28050efa50 fix: support fingerprint mode in client management operations (#1446)
## Summary

Fixes fingerprint mode (OpenVPN 2.6+ peer-fingerprint authentication)
which was broken for client management operations.

### CI Fix
Docker environment variables (`AUTH_MODE`, etc.) weren't being passed to
the systemd service running tests. Added `PassEnvironment` directive to
fix this.

### Script Fixes
In fingerprint mode, `easyrsa self-sign-*` commands don't
create/maintain `index.txt`, but several functions depended on it.

**Fixed operations:**
- `selectClient()`: uses fingerprints from server.conf instead of
index.txt
- `listClients()`: scans certs in pki/issued/, marks those without
fingerprint as revoked
- `newClient()`: duplicate check works in fingerprint mode, cleans up
revoked cert files for name reuse
- `revokeClient()`: removes fingerprint from server.conf, keeps cert for
listing
- `renewClient()`: uses `self-sign-client` instead of `easyrsa renew`
- `renewServer()`: uses `self-sign-server` + regenerates all client
configs (they embed server fingerprint)

**New helpers:**
- `getAuthMode()` - returns "pki" or "fingerprint"
- `getClientsFromFingerprints()` - parses client names from server.conf
- `clientExistsInFingerprints()` - checks client existence
- `getCertExpiry()` - extracts expiry date/days from cert file
- `removeCertFiles()` - removes cert/key/req files for regeneration
- `extractFingerprint()` - gets SHA256 fingerprint from cert

Fixes #1444
