✨ Add && separator for tags filter param on queryStatuses endpoint

[foysalit]

This PR adds a special separator character in the tags filter param array on tools.ozone.moderation.queryStatuses endpoint which allows moderators to filter queue items for multiple tags using the AND operator instead of the default OR operator which is applied between different items in the array.

So, currently, there is no way for a moderator to find all subjects that have both embed:image and lang:ja tags because passing tags: ['lang:ja', 'embed:image'] will return all items with either of the tags. This PR makes way for us to apply the expected filter using the syntax tags: ['lang:ja && embed:image']

Do we ignore empty queries ? Or maybe even throw an error ?

Suggested change

	return sql`(${sql.join(
	subTags.map(
	(subTag) =>
	sql`${ref('moderation_subject_status.tags')} ? ${subTag}`,
	),
	sql` AND `,
	)})`
	// False is neutral in a union ("OR")
	if (!subTags.length) return sql`FALSE`
	return sql`(${sql.join(
	subTags.map(
	(subTag) =>
	sql`${ref('moderation_subject_status.tags')} ? ${subTag}`,
	),
	sql` AND `,
	)})`

good catch! handled these edge cases through boolean filters.
