Add editing capability for non-AICS data sources

[aswallace]

Add editing capability for non-AICS data sources. This may already be addressed in the endpoint branch, but important to verify. If so, update ternary for edit modal in file access menu

Should be possible via SQL like:

UPDATE ${datasourceName}
SET ${columnToUpdate} = ${valueToReplaceWith}
WHERE ${here either select by row number or the internally made BFF ID} = ${list of row numbers or bff ids}
