Overview

Takes specific seats off sale on specific dates.

Writes one ReservedBlock with status :locked per (seat x date) and deducts 1 from that date's quantity_available. Both must move together: for seat-selection trips the numeric counter is still live (RedisStock::Unstock decrements it on order completion), so a lock that only wrote a row would leave the trip advertising seats nobody can book.

PARTIAL SUCCESS IS THE CONTRACT, not an edge case. Locking a seat across a month when one date is already sold must lock the other dates and report the skip.

success(applied: [ReservedBlock, ...], skipped: [{ date:, block_label:, reason: }, ...])

Takes block_ids rather than a variant: Block carries its own variant_id, and a trip's seat map can assign different seats to different fare-class variants, so a selection may span variants.
