* https://github.com/go-gitea/gitea/pull/31706
cc @earl-warren; as per discussion on https://github.com/go-gitea/gitea/pull/31632 this involves a small compatibility break (OIDC introspection requests now require a valid client ID and secret, instead of a valid OIDC token)

To fix the error, the client must begin sending HTTP basic authentication with a valid client ID and secret. This endpoint was previously authenticated via the introspection token itself, which is less secure.<!--description-->

Was facing issues while writing unit tests for federation code. Mocks weren't catching all network calls, because was being out of scope of the mocking infra. Plus, I think we can have more granular tests.
This PR puts the client behind an interface, that can be retrieved from `ctx`. Context doesn't require initialization, as it defaults to the implementation available in-tree. It may be overridden when required (like testing).
## Mechanism
1. Get client factory from `ctx` (factory contains network and crypto parameters that are needed)
2. Initialize client with sender's keys and the receiver's public key
3. Use client as before.

- If you have the external issue setting enabled, any reference would
have been rendered as an external issue, however this shouldn't be
happening to references that refer to issues in other repositories.
- Unit test added.
- Adjust the counting of the number of lines of a file to match the
amount of rendered lines. This simply means that a file with the content
of `a\n` will be shown as having `1 line` rather than `2 lines`. This
matches with the amount of lines that are being rendered (the last empty
line is never rendered) and matches more with the expecation of the
user (a trailing EOL is a technical detail).
- In the case there's no EOL, the reason why it was counting
'incorrectly' was to show if there was a trailing EOL or not, but now
text is shown to tell the user this.
- Integration test added.
- ResolvesCodeberg/Community#1612
- Adjust the `RepoRefByType` middleware to allow for commit SHAs that
are as short as 4 characters (the minium that Git requires).
- Integration test added.
- Follow up to 4d76bbeda7
- Resolves#4781
An instance-wide actor is required for outgoing signed requests that are
done on behalf of the instance, rather than on behalf of other actors.
Such things include updating profile information, or fetching public
keys.
