Summary:
Ref T10927. Pretty sure the issue is:
- User makes an HTTPS request.
- Load balancer terminates it, but with an `X-Forwarded-Proto` header.
- `secure001` (or whatever; acting as web host) proxies it to `secure002` (or whatever; acting as a repository host). **This** connection is plain HTTP.
- Since this proxied connection is plain HTTP, we check if the repository can serve over "http", but it can't: only "https". So we fail incorrectly, even though the original user request was HTTPS.
In the long run we should probably forward the `X-Forwarded-Proto` header, but that has some weird implications and it's broadly fine to allow either protocol to serve as long as the other one is active: configuration like `security.require-https` is already stronger than these settings.
Test Plan: This is likely only observable in production, but normal cloning still works locally.

Fixes T10912. When you drag tasks within a milestone, we currently apply an overbroad, API-focused rule and add the parent board's project. This logic was added fairly recently, as part of T6027, to improve the behavior of API-originated moves.
Later on, this causes the task to toggle in and out of the parent project on every alternate drag.
This logic is also partially duplicated in the `MoveController`.
- Add test coverage for this interaction.
- Fix the logic so it accounts for subproject / milestone columns correctly.
- Put all of the logic into the TransactionEditor, so the API gets the exact same rules.
Test Plan:
- Added a failing test and made it pass.
- Dragged tasks around within a milestone column:
- Before patch: they got bogus project swaps on every other move.
- After patch: projects didn't change (correct).
- Dragged tasks around between normal and milestone columns.
- Before patch: worked properly.
- After patch: still works properly.
Here's what the bad changes look like, the task is swapping projects with every other move:
{F1255957}
The "every other" is because the logic was trying to do this:
- Add both the parent and milestone project.
- Whichever one exists already gets dropped from the change list because it would have no effect.
- The other one then applies.
- In applying, it forces removal of the first one.
- Then this process repeats in the other direction the next time through.

Ref T10748. This allows an EditEngine form to be broken up into pages.
This is less powerful than `PHUIPagedFormView`, because the pages are not sequential / stateful. Each form saves immediately once it's submitted, and can not take you to a new form or back/forward in a series of forms.
For example, you can't create a workflow where the user fills out 5 pages of information before we create an object, like the current repository workflow does.
However, the only place we've ever wanted to do this is repositories and it's fairly bad there, so I feel reasonably confident we aren't going to miss this in the future.
(We do "choose a type of service/repository/rule -> fill out one page of info" fairly often, but can do this without the full-power paging stuff.)

Fixes T10876. Currently, we can end up with a setup warning banner sticking on each web device, since the state is stored in local cache.
Instead:
- When we actually run the setup checks, save the current state in the database.
- Before we show a cached banner, make sure the database still says the checks are a problem.
This could lead to some inconsistencies if setup checks legitimately pass on some hosts but not on others. For example, if you have `git` installed on one machine but not on another, we may raise a setup warning ("No Git Binary!") about it on one host only.
For now, assume users have their operational environments in some sort of reasonable shape and can install the same stuff everywhere. In the future, we could split the issues into "global" and "per-host" issues if we run into problems with this.
Test Plan:
This is somewhat tricky to test locally since you really need multiple webservers to test it properly, but I:
- Created some setup issues, saw banner.
- Ignored/cleared them, saw banner go away.
- Verified database cache writes were occurring properly.
Then I sort of faked it like this:
- Created a setup issue.
- Manually set the database cache value to `[]` ("no issues").

Ref T10860. This allows us to recover if the connection to the database is lost during a push.
If we lose the connection to the master database during a push, we would previously freeze the repository. This is very safe, but not very operator-friendly since you have to go manually unfreeze it.
We don't need to be quite this aggressive about freezing things. The repository state is still consistent after we've "upgraded" the lock by setting `isWriting = 1`, so we're actually fine even if we lost the global lock.
Instead of just freezing the repository immediately, sit there in a loop waiting for the master to come back up for a few minutes. If it recovers, we can release the lock and everything will be OK again.
Basically, the changes are:
- If we can't release the lock at first, sit in a loop trying really hard to release it for a while.
- Add a unique lock identifier so we can be certain we're only releasing //our// lock no matter what else is going on.
- Do the version reads on the same connection holding the lock, so we can be sure we haven't lost the lock before we do that read.
Test Plan:
- Added a `sleep(10)` after accepting the write but before releasing the lock so I could run `mysqld stop` and force this issue to occur.
- Pushed like this:

Summary:
Ref T10860. At least in Git over SSH, we can freely echo a bunch of stuff to stderr and Git will print it to the console, so we can tell users what's going on.
This should make debugging, etc., easier. We could tone this down a little bit once things are more stable if it's a little too chatty.
Test Plan:
```
