Add probes to Connector chart

Add configurable probes to the connector container:

- startupProbe: enabled by default, allows up to 2 minutes for startup
- readinessProbe: enabled by default, marks pod ready when /ready returns OK
- livenessProbe: disabled by default, can be enabled via values

All probe settings (path, port, thresholds, intervals) are customizable
through values while providing sensible defaults.
