Fix/aligned tv page seal (#734)
* fix readme logo
* fix readme logo
* fix readme badge
* tmp
* add ut
* mvn spotless:apply
* tmp
* try to fix ut
* Align C++ aligned-model page sealing with the Java behavior and fix
reader handling of null-only value pages so that Debug builds pass.
* fix ut
* Add strict_page_size switch to optimize aligned tablet writing.
In non-strict mode, disable per-write auto page sealing and seal value
pages at time-page boundaries to reduce overhead while preserving aligned page
semantics.
* fix QueryByRowFasterThanManualNext tolerance
* fix time_page_row_ends.reserve
