Sort labels with locale-aware collation (#9023)

Labels (tags) were sorted by the database's raw byte/ASCII collation
via ORDER BY name, so accented or non-Latin label names sorted after
all ASCII names instead of near their base letter.

Apply the same FreshRSS_Context::localeCompare() sort used for
categories, feeds, and shares (#8985) to TagDAO::listTags(), fixing
the last remaining sub-item of this issue; the others were already
resolved by #6212.

Fixes #6211
