#59580)

When restoring a view to a different database, the current
implementation incorrectly replaces **all** database names in the view
definition with the target database name. This breaks cross-database
references.

**Example:**
- Original: `view_db` has a view referencing tables from both `base_db`
and `view_db`
```sql
  SELECT * FROM `internal`.`base_db`.`table1` 
  JOIN `internal`.`view_db`.`table2`
```
  - After restore to `restore_db` (BEFORE this PR):
```sql
  SELECT * FROM `internal`.`restore_db`.`table1`  -- ❌ Wrong! Should be base_db
  JOIN `internal`.`restore_db`.`table2`           -- ✅ Correct
```
  - After restore to `restore_db` (AFTER this PR):
```sql
  SELECT * FROM `internal`.`base_db`.`table1`     -- ✅ Correct! Preserved
  JOIN `internal`.`restore_db`.`table2`           -- ✅ Correct
```
  **Root Cause:**
The regex pattern `(?<=\`internal\`\\.\`)([^\`]+)(?=\`\\.\`)` matches
**any** database name, not just the source database name.
