Eric Eastwood 46d235cd52 Add in-repo Complement tests (#19406) ...

This is useful so we can test Synapse
specific behaviors like our admin API.

(see docs in PR, `complement/README.md`)
```
COMPLEMENT_DIR=../complement ./scripts-dev/complement.sh --in-repo
```

Complement calls these
["out-of-repo"](https://github.com/matrix-org/complement/blob/78c255edcebfcb0ac5e3c86d49d76cb21fdd035a/OUT-OF-REPO-TESTS.md)
tests but it's a bit of a misnomer once they're in your project. (just
depends on the perspective)

There has been [previous
desire](https://github.com/element-hq/synapse/pull/19021#discussion_r2453442191)
for this kind of thing but this is spawning from wanting to have some
tests for our purge history admin API
(https://github.com/element-hq/synapse-rust-apps/issues/430). There are
some Sytest tests ([`matrix-org/sytest` ->
`tests/48admin.pl#L91-L618`](https://github.com/matrix-org/sytest/blob/1be04cce46c0f84abac736390dc3fab17f35a756/tests/48admin.pl#L91-L618))
for this already but I'd much rather work in Complement instead of
Sytest. I'm wanting these tests to ensure that our new `event-cache`
rust app for Synapse Pro doesn't break these kind of erasure features
(https://github.com/element-hq/synapse-rust-apps/issues/366 and
https://github.com/element-hq/synapse-rust-apps/issues/153).

Interestingly, there is already [`matrix-org/complement` ->
`tests/csapi/admin_test.go`](https://github.com/matrix-org/complement/blob/78c255edcebfcb0ac5e3c86d49d76cb21fdd035a/tests/csapi/admin_test.go)
(added in https://github.com/matrix-org/complement/pull/322) in the
Complement repo iteslf that tests the
`/_synapse/admin/v1/send_server_notice` endpoint but it's a bit of an
interesting case as [Dendrite also supports this
endpoint](https://github.com/matrix-org/dendrite/pull/2180). I don't
think it's good practice to continually shove in more and more
Synapse-specific behavior into the Complement repo itself.

We already have success with other out-of-repo tests for projects like
the
[SBG](https://github.com/element-hq/sbg/tree/b76b05b53e40bf6890e51dd1b83cec3460274eb2/complement_tests),
[TI-Messenger
Proxy](https://github.com/element-hq/ti-messenger-proxy/tree/c8fa87feccc743c01cccbbc2685321206b532925/complement),
and our [Synapse Pro for small
hosts](https://github.com/element-hq/synapse-small-hosts/tree/c2ea7eabf3e1d7c26a5312ebef326b254937be99/complement).
