🤖 fix: reduce noisy reconcile errors and align CNPG access URL

[ThomasK33]

Summary

This change reduces noisy controller logs by removing immediate cached read-after-write lookups after successful CreateOrUpdate operations in the control plane and workspace proxy reconcilers. It also aligns the CloudNativePG example to use http://localhost:3000 for CODER_ACCESS_URL and matching quickstart instructions.

Background

When reconcilers created resources and immediately performed a cached Get, controller-runtime cache propagation could briefly lag API writes, producing transient NotFound errors. In dev logging mode those surfaced with stack traces that looked panic-like despite being recoverable retries.

Implementation

• Removed immediate post-CreateOrUpdate Get calls in:
  • internal/controller/codercontrolplane_controller.go
  • internal/controller/workspaceproxy_controller.go
• Added comments explaining why cached read-after-write is intentionally avoided.
• Updated CloudNativePG example access URL:
  • examples/cloudnativepg/codercontrolplane.yaml (CODER_ACCESS_URL=http://localhost:3000)
  • examples/cloudnativepg/README.md (port-forward/open URL/URL note updated to 3000)

Validation

• make test
• make test-integration
• make build
• make lint
• KIND smoke check: restarted operator, deleted coder Service, verified recreation without new Reconciler error log lines.
• make verify-vendor currently fails in this environment due an upstream checksum mismatch while running go mod tidy for github.com/MirrexOne/unqueryvet v1.4.0 (downloaded checksum differs from the existing go.sum entry).

Risks

• Low risk. Reconciler behavior is unchanged for desired state convergence; this removes only an immediate cache read that could be stale.
• Status readiness remains eventually consistent (as before) and is naturally advanced on subsequent reconcile events.
