multiple pages with same name

@megayu is already working on this.

Since Aug 17, 2026.

### Search first

- [x] I searched and no similar issues were found

### What Happened?

I somehow ended up having multiple pages with the same name.

### Reproduce the Bug

1. the graph was imported from OG
2. i added some new blocks every now and then to test syncing

### Expected Behavior

Since this is not allowed, it should not happen. I think the validation should also fail.

### Screenshots

### Files

Original imported page:

### Additional Context

The second page seem to have been introduced on 2026-06-29 by copy and pasting a whole days journal from OG to DB.

This also happened with "Social Media". I had 3 pages and 2 blocks with the same name that show up in the suggestions when i type "social " in link. Once i added a link to the blocks, they seem to have become pages and where introduced by that link itself, like a circular dependency. I added links to all 5 of those on that journal page. While editing, i see different UUIDs instead of the title.

I can not reproduce this by adding a block with the text "Social Media" and then create a link to it. That correctly links to the block itself and not a page. The data was probably messed up by an earlier version.
