Long ago, there were different types of feed stories. Over time, there was less and less need for this, and nowadays basically everything is a "transaction" feed story. Each story renders differently, but they're fundamentally all about transactions.
The Notification test controller still uses a custom type of feed story to send notifications. Move away from this, and apply a transaction against the user instead. This has the same ultimate effect, but involves less weird custom code from ages long forgotten.
This doesn't fix the actual problem with these things showing up in feed. Currently, stories always use the same rendering for feed and notifications, and there need to be some additional changes to fix this. So no behavioral change yet, just slightly more reasonable code.
Test Plan: Clicked the button and got some test notifications, with Aphlict running.

Summary:
Ref T13222. See PHI683. Currently, you can "Change subtype..." via Conduit and the bulk editor, but not via the comment action stack or edit forms.
In PHI683 an install is doing this often enough that they'd like it to become a first-class action. I've generally been cautious about pushing this action to become a first-class action (there are some inevitable rough edges and I don't want to add too much complexity if there isn't a use case for it) but since we have evidence that users would find it useful and nothing has exploded yet, I'm comfortable taking another step forward.
Currently, `EditEngine` has this sort of weird `setIsConduitOnly()` method. This actually means more like "this doesn't show up on forms". Make it better align with that. In particular, a "conduit only" field can already show up in the bulk editor, which is goofy. Change this to `setIsFormField()` and convert/simplify existing callsites.
Test Plan:
There are a lot of ways to reach EditEngine so this probably isn't entirely exhaustive, but I think I got pretty much anything which is likely to break:
- Searched for `setIsConduitOnly()` and `getIsConduitOnly()`, converted all callsites to `setIsFormField()`.
- Searched for `setIsLockable()`, `setIsReorderable()` and `setIsDefaultable()` and aligned these calls to intent where applicable.

I kept the "is admin" permissions check for consistency, since these methods have always said "(admin only)". This check may not be the most tailored check soon, but we can just keep executing it in addition to the real check.
For now, this change stops this method from actually disabling non-bot users (since it implicitly adds a CAN_EDIT requirement, and even administrators don't have that). An upcoming change will fix that.
Test Plan: Enabled and disabled a (bot) user via these methods. Checked API UI, saw them marked as "disabled".

Currently, this also doesn't let you disable normal users even when you're an administrator. I'll refine the policy model later in this change series, since that's also the goal here (let users set "Can Disable Users" to some more broad set of users than "Administrators").
This also leaves us with two different edit pathways: the old UserEditor one and the new UserTransactionEditor one. The next couple diffs will redefine the other pathways in terms of this pathway.
Test Plan:
- Enabled/disabled a bot.
- Tried to disable another non-bot user. This isn't allowed yet, since even as an administrator you don't have CAN_EDIT on them and currently need it: right now, there's no way for a particular set of transactions to say they can move forward with reduced permissions.

Ref T7152. This builds the core of email invites and implements all the hard logic for them, covering it with a pile of tests.
There's no UI to create these yet, so users can't actually get invites (and administrators can't send them).
This stuff is a complicated mess because there are so many interactions between accounts, email addresses, email verification, email primary-ness, and user verification. However, I think I got it right and got test coverage everwhere.
The degree to which this is exception-driven is a little icky, but I think it's a reasonable way to get the testability we want while still making it hard for callers to get the flow wrong. In particular, I expect there to be at least two callers (one invite flow in the upstream, and one derived invite flow in Instances) so I believe there is merit in burying as much of this logic inside the Engine as is reasonably possible.

Small step forward which improves existing stuff or lays groudwork for future stuff:
- Currently, to check for email verification, we have to single-query the email address on every page. Instead, denoramlize it into the user object.
- Migrate all the existing users.
- When the user verifies an email, mark them as `isEmailVerified` if the email is their primary email.
- Just make the checks look at the `isEmailVerified` field.
- Add a new check, `isUserActivated()`, to cover email-verified plus disabled. Currently, a non-verified-but-not-disabled user could theoretically use Conduit over SSH, if anyone deployed it. Tighten that up.
- Add an `isApproved` flag, which is always true for now. In a future diff, I want to add a default-on admin approval queue for new accounts, to prevent configuration mistakes. The way it will work is:
- When the queue is enabled, registering users are created with `isApproved = false`.
- Admins are sent an email, "[Phabricator] New User Approval (alincoln)", telling them that a new user is waiting for approval.
- They go to the web UI and approve the user.
- Manually-created accounts are auto-approved.
- The email will have instructions for disabling the queue.
I think this queue will be helpful for new installs and give them peace of mind, and when you go to disable it we have a better opportunity to warn you about exactly what that means.
Generally, I want to improve the default safety of registration, since if you just blindly coast through the path of least resistance right now your install ends up pretty open, and realistically few installs are on VPNs.
Test Plan:
- Ran migration, verified `isEmailVerified` populated correctly.
- Created a new user, checked DB for verified (not verified).
