Fix partial args matching

[JUVOJustin]

partial_args_matching (json and like modes) fails to find actions when arguments exceed 191 characters because it only queries the args column, which contains an MD5 hash for long args while the actual JSON is in extended_args.

Changes

• json mode: Use COALESCE(a.extended_args, a.args) so JSON_EXTRACT operates on actual JSON data
• like mode: Check both columns following the existing search query pattern: ((a.extended_args IS NULL AND a.args LIKE %s) OR a.extended_args LIKE %s)

Example

// Before: only checks args column (contains MD5 hash for long args)
$sql .= ' AND JSON_EXTRACT(a.args, %s)=' . $placeholder;

// After: checks extended_args first if present
$sql .= ' AND JSON_EXTRACT(COALESCE(a.extended_args, a.args), %s)=' . $placeholder;

Tests

Added test coverage for both like and json modes with:

• Short args (≤191 chars, stored in args)
• Long args (>191 chars, stored in extended_args)
