fix: show resolved absolute path in permission dialog, restore buffer.rs

When the LLM sends malformed paths like '1' as a write target,
the permission dialog showed 'path: 1 (inside project)' which
confused users — they couldn't tell what file would be modified.
Now shows both the raw input AND the resolved absolute path:
'path: 1 → /home/user/project/1 (inside project)'.

Also reverted ui/buffer.rs corruption from botched merge.
