Fix MicroShift/e2e install timeout and simplify deploy

[kush982]

Pull request description

Remove helm --wait for operator install; rely on kubectl waits to avoid context deadline exceeded under e2e label.
Make operator values OpenShift-compatible (unset runAsUser/runAsGroup) and default to cluster StorageClass; keep templates clean and placeholders intact.

Testing Approach
E2E tests were validated by running workflows directly on the fix/microshift_tests branch rather than using the e2e label. This was necessary because the workflows were using pull_request_target, which reads workflow files from the base branch (main) instead of the PR branch, causing workflow configuration changes to be ignored.
Why Direct Branch Testing Was Required
When using the e2e label with pull_request_target:
❌ Workflow files are read from main branch (not PR branch)
❌ Workflow changes in this PR (like TF_REPO_REF: fix/crowd-db-restore) were ignored
❌ Tests ran with outdated configuration

When running workflows directly on the branch:
✅ Workflow files are read from PR branch (fix/microshift_tests)
✅ All workflow changes included (CloudNativePG fixes, Terraform branch override)
✅ Tests ran with correct configuration

Successful Test Runs
All E2E tests passed successfully on the PR branch:
MicroShift Tests (All Products):
Run #18885444887 - ✅ All products passed (Jira, Confluence, Bitbucket, Bamboo, Crowd)
Run #18884943041 - ✅ All products passed
E2E Terraform Tests:
Run #18885444899 - ✅ Infrastructure deployment and E2E tests passed
Run #18882051203 - ✅ Full E2E suite passed (1h runtime)

Checklist

• I have added unit tests
• I have applied the change to all applicable products
• The E2E test has passed (use e2e label)
