[Filter] Restore exact, case-insensitive set code search (#7336)

* [Filter] Restore exact, case-insensitive set code search (#7332, #7333)

* [Filter] Group set query suffix modes into a subrule

Address review feedback: keep the 'e'/'set' prefix in one place and move
the three suffix modes (exact, negated, release-date comparison) into a
dedicated choice-like rule so sv.choice() still dispatches on them.

Add coverage for the release-date comparison mode.
