SIMSBIOHUB-874: Ensure GitHub workflows clean up ImageStream tags

• SIMSBIOHUB-874

Description of Changes

• Single cleanup workflow: Renamed cleanClosedPR.yml to cleanPR.yml. It now runs whenever a PR is closed (merged or not) or converted back to draft, and removes that PR’s Helm release in dev plus all four image tags (app, api, db, db-setup) in -tools. We no longer have separate workflows for “closed” vs “merged.”
• Removed cleanMergedPR.yml — its behaviour is covered by the updated cleanPR workflow.
• deployStatic.yml: Replaced the post-deploy “clean” job with “pruneOldImageTags.” After a merge or manual run, we now prune old image tags for that environment (dev/test/prod) and keep only the 3 most recent per image, so ImageStream doesn’t accumulate tags. PR-specific cleanup is handled by cleanPR when the PR closes.
• cleanPR tweaks: 20-minute timeout, and DB Setup image tag delete is now non-fatal if the tag doesn’t exist (aligned with the other images).

Testing Notes

• Close a PR without merging and confirm cleanPR runs and removes the Helm release and the four image tags in -tools.
• Merge a PR and confirm cleanPR runs and that deployStatic’s prune job keeps only the 3 most recent tags per image for that branch.
• Convert a PR to draft and confirm cleanPR runs.
• Optionally run deployStatic via workflow_dispatch and confirm the prune step completes without errors.
