Fixed wrongly handled not ready TSDB on web and API. (#7182)
* fix federate endpoint panic

Signed-off-by: yeya24 <yb532204897@gmail.com>

* Fixed all cases of not ready TSDB being wrongly handled.

* Fixed issue for federation.
* Ensured this will never happen again thanks to interfaces
* Fixes same issue for stats.
* Added tests for readiness.
* Fixed bug in stats. It was:
   status.MaxTime = db.Head().MaxTime()
   status.MinTime = db.Head().MaxTime()
