fix(platform-chart): add observability-alert-rule to web-application ComponentType allowedTraits

[senithkay]

Summary

• deployment_spec.go attaches the observability-alert-rule ClusterTrait to all deployment components (service and web-application) when ResolveAutoRCAEnabled is true (see alert_rule_trait.go:DesiredObservabilityAlertRuleTraits)
• The web-application ComponentType had no allowedTraits field at all, so OC rejected release generation for every webapp component with: traits [ClusterTrait:observability-alert-rule] are not in the allowed list []
• This is the same class of bug as fix(platform-chart): add observability-alert-rule to service ComponentType allowedTraits #590 (which fixed service), just for the web-application ComponentType
• Web-application components don't expose a managed API gateway path, so only observability-alert-rule is needed (no api-configuration)

Proof

Live cluster blocked with this error (expense-webapp in mm1):

run: deploy failed: component "expense-webapp": cut release: generate release: bad request: validation error: traits [ClusterTrait:observability-alert-rule] are not in the allowed list []

Live fix applied:

kubectl patch componenttype web-application -n default --type=merge \
  -p '{"spec":{"allowedTraits":[{"kind":"ClusterTrait","name":"observability-alert-rule"}]}}'

componenttype.openchoreo.dev/web-application patched ✓
