Add complete_match: one BEGIN/COMMIT that validates identity + result,
enforces a durable (profile_id, match_identity) uniqueness guard
(migration 0022 match_completions), persists match history, and grants
coins + XP/level-ups + W/D/L/DNF statistics + objectives + achievements
exactly once. Any failure rolls the whole match back (no compensating
cleanup). Handles sequential/restart/concurrent replay, conflicting
re-report (first result canonical), DNF (loss economics, own stat
bucket) and no-contest (zero economic effect).
Adds tx-scoped variants: statistics::record_match_tx/
record_position_goals_tx, objective::increment_metric_tx,
achievement::check_and_unlock_tx. New MatchResultKind/CompleteMatchRequest/
MatchCompletionResult models + POST /matches/complete route.
18 data-driven achievements (achievements.json) across 8 trigger categories:
matches_played, matches_won, goals_scored, packs_opened, sbcs_completed,
cards_owned, level, objectives_completed, drafts_completed. Rarities span
common → epic. Coin rewards range from 500 (first_match) to 6000 (win_50).
check_and_unlock() queries the relevant metric from existing tables, skips
already-earned achievements via INSERT OR IGNORE, grants coin rewards, and
fires a persistent notification per unlock. Trigger values are cached per
call to avoid redundant DB round-trips for same-trigger achievements.
Checks run automatically after every match result (all triggers), every
pack open (packs_opened), and every successful SBC submission (sbcs_completed).
GET /achievements returns all definitions annotated with unlocked/unlocked_at,
plus earned and total counts. POST /matches/result response gains an
achievements_unlocked array (empty when nothing new unlocked).
AppState gains achievement_defs (Arc<Vec<AchievementDefinition>>) loaded
from data/achievements/**/*.json at startup — same pattern as obj_defs.
5 new tests: list endpoint, first_match unlock, first_win unlock, no-dup
guard, coin reward verification. Core now at 82 tests.

XP thresholds (500→1200→2000→…→11000→+2500/level) drive automatic level
increases. add_xp_with_levelup() replaces bare add_xp() in match
processing: for each level gained it grants level×500 coins and milestone
packs (bronze@5, silver@10, gold@15, rare_gold@20, gold every 5 after).
GET /profile now returns computed level (recalculated from XP so it
stays consistent), xp_to_next_level, and xp_for_next_level so the
dashboard can render a progress bar without a second call.
POST /matches/result response gains level_ups array (empty when no
level-up occurred) with new_level, coins_granted, pack_granted per event.
Four new tests: profile level fields, level_for_xp boundary checks,
level-up event in match result, milestone pack unit test.
