fix(historian): SQL quality contract, long-name refusal, info-bit masking, AtTime-after-now, bootstrap hardening

- I-1: an Empty sample is always Bad. The writer stores a non-Bad NaN/Inf as
  Empty+BadOutOfRange and any other non-Bad Empty as BadNoData; the updater
  refuses a non-Bad Empty with BadInvalidArgument; reads clamp a legacy
  non-Bad Empty row to BadNoData (Raw and AtTime).
- Tag/source names over 400 chars are refused, never truncated: writer
  per-tag failure, updater BadInvalidArgument, reads not-found, events none.
- HistorianInfoBits masks the historian bits before setting one.
- AtTime past now, stepped from the last sample => UncertainDataSubNormal.
- Bootstrapper: logger, 5 s negative cache, ClearPool + Warning when
  sp_releaseapplock fails.
- Provider builds its shared state lazily (an invalid Schema no longer
  throws at Resolve); Kinds is a FrozenSet; Gateway reuses the recorder's
  DefaultSupportedKinds.
- Cleanup: SqlHistorianDataTypes in its own file (updater dup removed),
  dead Invalidate and unused status consts deleted, named severity masks,
  alarm writer brace.
