Minor cleanups June 2026

In the spirit of previous such PRs, this PR proposes a collection of nonfunctional changes.

I am happy to incorporate changes from other devs, and revert some of the proposed changes if the maintainers ask me to.

Apart from trivial changes, the proposed changes so far include:

* A requested edit to `AUTHORS` and a resorting of all entries, following DIN 5007 for the treatment of any special characters.
* Exclude the two recent integer type renaming commits from git blame.
* Tightening of some static asserts in `history.h` to avoid overflows. (Note that rounding errors for floating point types could lead to the assert in `operator<<` triggering at run-time.)
* Re-instate the 0.5s maximal thinking time in case of a single legal move and reword the comment to make it clear that it should not be tuned.
* ~~A small refactoring of the network loading code thanks to @dubslow.~~
* A refactoring of the "dtz is dtm" code, also thanks to @dubslow.
