Enforce the reminder nag cap, compare the disclaimer version, drop the unread analytics columns

- The daily Coach sweep now charges each ignored day against
  surfaceCount and auto-dismisses at three — the cap the schema comment
  promised since v1.22 but nothing enforced.
- The welcome gate compares the stored disclaimer acknowledgment
  version against the current one, so revised disclaimer text
  re-prompts; /api/auth/me carries the version for the client.
- slope90 and anomalyCount leave the analytics wire: slope90 had no
  reader anywhere (computed on every request, in SQL twice), and the
  slim path could never compute anomalyCount (it always reported 0).
  anomalyCount stays as an in-process field on summarize() for the
  insights feature builder, which is its only real consumer.
