Add printer columns to all CRDs

[ChrisJBurns]

Summary

• kubectl get output for config CRDs was minimal (just name + age), forcing operators to use -o yaml to check readiness or discover which MCPServers reference a config. This adds informative printer columns to all config CRDs and fixes inconsistencies found during audit.
• Adds Ready and References columns to MCPOIDCConfig, MCPTelemetryConfig, MCPExternalAuthConfig, and MCPToolConfig. Fixes the MCPGroup printerColumn marker typo that silently prevented column rendering.

Closes #4252

Type of change

• New feature

Test plan

• Unit tests (task test)
• Linting (task lint-fix)
• CRD manifest regeneration (task operator-manifests) — verified generated YAML matches markers

Changes

File	Change
mcpoidcconfig_types.go	Rename "Type" → "Source", add Ready + References columns

mcpgroup_types.go	Fix printerColumn typo → printcolumn, reorder columns
toolconfig_types.go	Remove broken Filter/Override Count columns, add Ready
deploy/charts/operator-crds/**	Regenerated CRD manifests (files + templates)

Does this introduce a user-facing change?

Yes. kubectl get output is now significantly more informative for all CRDs:

MCPOIDCConfig — before:

NAME              TYPE                       AGE
my-oidc-config    kubernetesServiceAccount   5m

MCPOIDCConfig — after:

NAME              SOURCE                     READY   REFERENCES              AGE
my-oidc-config    kubernetesServiceAccount   True    ["my-server","other"]   5m

MCPTelemetryConfig — before:

NAME              ENDPOINT                        TRACING   METRICS   AGE
my-otel-config    https://otel-collector:4318     true      true      5m

MCPTelemetryConfig — after:

NAME              ENDPOINT                        READY   REFERENCES       AGE
my-otel-config    https://otel-collector:4318     True    ["my-server"]    5m

MCPExternalAuthConfig — before:

NAME              TYPE              AGE
my-auth-config    tokenExchange     5m

MCPExternalAuthConfig — after:

NAME              TYPE              READY   REFERENCES       AGE
my-auth-config    tokenExchange     True    ["my-server"]    5m

MCPToolConfig — before:

NAME             FILTER COUNT   OVERRIDE COUNT   REFERENCED BY      AGE
my-tool-config                                   ["my-server"]      5m

MCPToolConfig — after:

NAME             READY   REFERENCES       AGE
my-tool-config   True    ["my-server"]    5m

MCPGroup — before (columns silently missing due to typo):

NAME       READY    AGE
my-group   True     5m

MCPGroup — after (all columns now render):

NAME       SERVERS   PHASE   READY   AGE
my-group   3         Ready   True    5m

Special notes for reviewers

• The MCPGroup had three +kubebuilder:printerColumn markers (capital C) which is not a recognized kubebuilder marker — only +kubebuilder:printcolumn works. This means the Servers, Phase, and Age columns were silently dropped from the generated CRD. Only the Ready column (which used the correct spelling) was rendering.
• Config CRDs use a "Valid" condition type (not "Ready") for their status, so the Ready column maps to .status.conditions[?(@.type=='Valid')].status.
• MCPToolConfig's previous "Filter Count" and "Override Count" columns used type=integer with JSONPaths that resolve to arrays/maps, not integers — they produced empty output. Replaced with a Ready column.
