feat(server): use infix search for originalPath property

[C-Otto]

For uploaded files, the originalPath column sadly doesn't contain anything interesting. However, for users of external libraries, the path might contain very helpful information:

• /home/user/pictures/vacations/1999/southpole/
• /home/user/pictures/weddings/2024/adam_and_eve/
• /home/user/pictures/random_snapshots/
• ...

Query URLs like the following already work for originalFilename:

/search?query={"originalFileName":"IMG_123"}

For users who dare to manually change this to include originalPath instead, the pre-PR code also works, but only checks for an exact match of the value. This PR merely changes this to look for infixes, mirroring the behavior of originalFileName. This way, one can limit searches accordingly:

/search?query={"originalPath":"adam_and_eve"}

I believe you have to create similar index for the original file name column as well

I believe you have to create similar index for the original file name column as well

You mean originalPath? I see both a plain index (1705306747072-AddOriginalFileNameIndex) and a trigram index (1709608140355-AddAssetOriginalPathTrigramIndex). Should I add both?

Note that the file name of the trigram migration is misleading, it's adding an index for originalFileName, not originalPath.
