helm: gate worker hub token on the same condition as hub AUTH_ENABLED (#1954)

The hub's AUTH_ENABLED is derived from cloudLicenseEnabled/demoModeEnabled/
tap.auth.enabled, but the worker DaemonSet gated HUB_INTERNAL_TOKEN_PATH, its
volumeMount and the projected serviceAccountToken on tap.auth.enabled alone.
With demoModeEnabled: true (or the default cloudLicenseEnabled: true) and
tap.auth.enabled unset, the hub required a bearer token the workers never got,
so every worker -> hub call returned 401: tracer target refresh and name
resolution history silently stopped while capture kept working.

Extract the condition into a kubeshark.authEnabled helper and consume it from
both 12-config-map.yaml and 09-worker-daemon-set.yaml so the two cannot drift.
AUTH_ENABLED renders identically to before for all combinations of
cloudLicenseEnabled/license/demoModeEnabled/tap.auth.enabled/tap.auth.type.
