Raises backend test coverage toward 90% (spec specs/todos/2026-10-23-03-coverage-90.md, still in specs/todos/: not done).

What changed

• Full Postgres layer: 85.26% -> 88.3% (filtered with scripts/coverage.sh). 90% is not reached, about 1.7 points (~2700 statements) remain.
• New shared DB dialect contract (server/internal/db/dbcontract/) run on SQLite and Postgres: orgs, severities, groups, maintenance, SLOs, escalation, on-call, dependencies, providers, tokens, passkeys, status pages, connections, events, labels, results, agents and enrollment tokens, contacts, notifications, publications.
• Tests for handlers/checks dependencies and listing, checkminecraft, cmd/scenariodriver, cmd/loadgen, cmd/membench.
• Ratchet: COVERAGE_MIN and Codecov targets raised from 80 to 88; wiki/testing/test-layers.md and wiki/testing/coverage.md updated.
• No code excluded from the profile. No runtime behaviour change.

Remaining (next ticks)

Contract groups for device auth, state entries/events, check versions; handler tests for checks (clone, import), auth, incidents, integrations, statuspages, usernotifications, incidentpublications, telegramcb, agents; pkg/cli, jobs/jobtypes, slack/discord/msteams, mcp, small checkers. Not live-network or Docker code, a long tail of error branches.

Decided by autopilot

• specs/todos/2026-10-23-03-coverage-90.md, open question (90% on which layer): the full Postgres layer, the number CI and Codecov report.
