fix(FR-2467): disable session commit button until session is Running (#6452)

Resolves #6443 (FR-2467)

## Summary
- Disable commit button when session status is not RUNNING
- Previously only checked isActive() which allowed non-running states like PREPARING, PENDING, PULLING to enable the button

## Test plan
- [ ] Verify commit button is disabled when session is in PREPARING state
- [ ] Verify commit button is disabled when session is in PENDING state
- [ ] Verify commit button is enabled when session is in RUNNING state
- [ ] Verify commit button remains disabled for non-owners regardless of session status
