fix: strip whitespace from workflow secret names (fixes #5326)

[DragonBot00]

Summary

Fixes #5326 — Secrets named with trailing/leading whitespace (e.g. "MY_SECRET ") appeared in the UI but could not be deleted, updated, or accessed.

Root Cause

When a secret was saved with a trailing space in the key (e.g. "MY_SECRET "), it was stored verbatim. Subsequent lookups or deletions using the trimmed name ("MY_SECRET") did not match the stored key, causing 404 errors or silent misses.

Changes

Backend: keep/api/routes/workflows.py

• write_workflow_secret: Strip whitespace from all incoming secret keys before storing — {k.strip(): v for k, v in secret_data.items()}
• delete_workflow_secret: Strip whitespace from the secret_name path parameter before lookup

Frontend: keep-ui/app/(keep)/workflows/[workflow_id]/workflow-secrets.tsx

• handleAddSecret: Trim the secret name before passing to the API so trailing spaces are caught at the UI level too

Testing

• Create a secret with trailing spaces in the name → it is stored without them
• Delete a secret → works correctly even if whitespace was in the original request
• Existing secrets without spaces are unaffected

Fixes: #5326
