When `webhook.PROXY_URL` has been set, the old code will check if the
proxy host is in `ALLOWED_HOST_LIST` or reject requests through the
proxy. It requires users to add the proxy host to `ALLOWED_HOST_LIST`.
However, it actually allows all requests to any port on the host, when
the proxy host is probably an internal address.
But things may be even worse. `ALLOWED_HOST_LIST` doesn't really work
when requests are sent to the allowed proxy, and the proxy could forward
them to any hosts.
This PR fixes it by:
- If the proxy has been set, always allow connectioins to the host and
port.
- Check `ALLOWED_HOST_LIST` before forwarding.
Previously, there was an `import services/webhooks` inside
`modules/notification/webhook`.
This import was removed (after fighting against many import cycles).
Additionally, `modules/notification/webhook` was moved to
`modules/webhook`,
and a few structs/constants were extracted from `models/webhooks` to
`modules/webhook`.

When re-retrieving hook tasks from the DB double check if they have not
been delivered in the meantime. Further ensure that tasks are marked as
delivered when they are being delivered.
In addition:
* Improve the error reporting and make sure that the webhook task
population script runs in a separate goroutine.
* Only get hook task IDs out of the DB instead of the whole task when
repopulating the queue
* When repopulating the queue make the DB request paged

_This is a different approach to #20267, I took the liberty of adapting
some parts, see below_
## Context
In some cases, a weebhook endpoint requires some kind of authentication.
The usual way is by sending a static `Authorization` header, with a
given token. For instance:
- Matrix expects a `Bearer <token>` (already implemented, by storing the
header cleartext in the metadata - which is buggy on retry #19872)
- TeamCity #18667
- Gitea instances #20267
- SourceHut https://man.sr.ht/graphql.md#authentication-strategies (this
is my actual personal need :)
## Proposed solution
Add a dedicated encrypt column to the webhook table (instead of storing
it as meta as proposed in #20267), so that it gets available for all
present and future hook types (especially the custom ones #19307).
This would also solve the buggy matrix retry #19872.
As a first step, I would recommend focusing on the backend logic and
improve the frontend at a later stage. For now the UI is a simple
`Authorization` field (which could be later customized with `Bearer` and
`Basic` switches):

The header name is hard-coded, since I couldn't fine any usecase
justifying otherwise.
## Questions
- What do you think of this approach? @justusbunsi@Gusted@silverwind
- ~~How are the migrations generated? Do I have to manually create a new
file, or is there a command for that?~~
- ~~I started adding it to the API: should I complete it or should I
drop it? (I don't know how much the API is actually used)~~
## Done as well:
- add a migration for the existing matrix webhooks and remove the
`Authorization` logic there
_Closes #19872_
