feat(plugin-access-manager): add optional configurable startupProbe for identity and auth

[gandalf-at-lerian]

What

Adds an optional, configurable startupProbe to the identity and auth components of the plugin-access-manager chart, following the existing readiness/liveness probe pattern.

Why

GitOps needs to configure startup probes for the identity and auth components so slow-starting pods get more time before liveness/readiness probes take over. The chart previously only had readiness/liveness probes.

Details

• Disabled by default; enabled via identity.startupProbe.enabled / auth.startupProbe.enabled.
• All fields override chart defaults, mirroring the readiness/liveness convention.
• Suggested defaults: failureThreshold: 5, periodSeconds: 10, timeoutSeconds: 10.
• httpGet defaults to /health on the component service port.

Files changed

• charts/plugin-access-manager/templates/identity/deployment.yaml
• charts/plugin-access-manager/templates/auth/deployment.yaml
• charts/plugin-access-manager/values.yaml
• charts/plugin-access-manager/Chart.yaml (version 8.2.0 -> 8.3.0)
• charts/plugin-access-manager/CHANGELOG.md

Verification

helm template renders the startupProbe for both components when enabled (identity port 4000, auth port 4001) and omits it when disabled (default). Output validated locally.
