Fix dynamo key queries to use trailing slashes for accurate repo matching (#7632)

###  Problem

Queries using dynamoKey LIKE 'pytorch/pytorch%' incorrectly match
commits from pytorch/pytorch-integration-testing, causing (among else)
autorevert to process "ghost commits" that don't exist in
pytorch/pytorch.

###  Solution

  Add trailing slash/delimiter to LIKE patterns:
- push table: pytorch/pytorch//% (double slash matches {repo}//{uuid}
format)
- Other tables: pytorch/pytorch/% (single slash matches {repo}/{id}
format)


---

### Testing

autorevert:
```
python -m pytorch_auto_revert --dry-run autorevert-checker pull --hours 12 --hud-html
```

rest: manual query run.
