Add the Analytics section: check runs, analytics API and page

Runs (migration 0011): a run groups the cycles of one launch. It opens when an
address enters an idle queue, takes everything submitted or re-checked while it
is open and is finalized when all its addresses are done; a re-check after that
opens a new run, so results of different runs never mix. check_runs,
run_results (one result per address and run, with the verdict and the expected
and stored check counts), subnets, run_id on ip_queue and checks. Existing data
is split into runs at pauses of more than an hour; ingress checks get the
validator that held the address (also at write time from now on).

Analytics (internal/analytics): figures computed from the stored checks of the
latest cycle of each address in the run, as facts next to the verdict: summary,
reasons of partial, data quality, subnets, targets and the subnet x target
matrix by check type, ingress by site, error classes, validators, and the
address lists behind the indicators and error classes. API: analytics runs,
report, lists (JSON or CSV), subnet list; run and subnet filters for the
registry.

Dashboard: /analytics matching the approved mockup (run selector, indicators
with address lists and CSV, error-class dialogs, drill-down to the registry),
subnet list on /settings. Sidebar: the control-api link state, theme toggle and
logout moved to the top, the three dots next to the logo removed, sections
grouped.

Rebuilt bin/control-api and bin/admin-dashboard to match. Plan, summary and the
updated README, API, USAGE, DASHBOARD and ADMIN_CLEANUP docs are in docs/.
