20c22eb159 Fix flaky expires_at tests
The API parameter is not a timestamp but an offset.
If a sufficient amount of time passes between the tests
expires_at calculation and the internal calculation during processing
of the request the strict equality assertion fails. (Either a direct
assertion or indirect via job lookup).

To avoid this lower comparison granularity.

literally nothing uses C2S AP, and it's another route into core
systems which requires analysis and maintenance. A second API
is just extra surface for potentially bad things so let's take

75d9e2b375 MRF.InlineQuotePolicy: Add link to post URL, not ID
"id" is used for the canonical link to the AS2 representation of an object.
"url" is typically used for the canonical link to the HTTP representation.
It is what we use, for example, when following the "external source" link
in the frontend. However, it's not the link we include in the post contents
for quote posts.

Using URL instead means we include a more user-friendly URL for Mastodon,
and a working (in the browser) URL for Threads

05f8179d08 check if data is visible before embedding it in OG tags
previously we would uncritically take data and format it into
tags for static-fe and the like - however, instances can be
configured to disallow unauthenticated access to these resources.

this means that OG tags as a vector for information leakage.

_technically_ this should only occur if you have both
restrict_unauthenticated *AND* you run static-fe, which makes no
sense since static-fe is for unauthenticated people in particular,
but hey ho.

bd74ad9ce4 Accept body parameters for /api/pleroma/notification_settings
This brings it in line with its documentation and akkoma-fe’s
expectations. For backwards compatibility URL parameters are still
accept with lower priority. Unfortunately this means duplicating
parameters and descriptions in the API spec.

Usually Plug already pre-merges parameters from different sources into
the plain 'params' parameter which then gets forwarded by Phoenix.
However, OpenApiSpex 3.x prevents this; 4.x is set to change this

464db9ea0b Don't list old accounts as aliases in WebFinger
Per the XRD specification:

> 2.4. Element <Alias>
>
> The <Alias> element contains a URI value that is an additional
> identifier for the resource described by the XRD. This value
> MUST be an absolute URI. The <Alias> element does not identify
> additional resources the XRD is describing, **but rather provides
> additional identifiers for the same resource.**

(http://docs.oasis-open.org/xri/xrd/v1.0/os/xrd-1.0-os.html#element.alias, emphasis mine)

In other words, the alias list is expected to link to things which are
not just semantically the same, but exactly the same. Old user accounts
don't do that

This change should not pose a compatibility issue: Mastodon does not
list old accounts here (See e1fcb02867/app/serializers/webfinger_serializer.rb (L12))

The use of as:alsoKnownAs is also not quite semantically right here
(see https://www.w3.org/TR/did-core/#dfn-alsoknownas, which defines
it to be used to refer to identifiers which are interchangable) but
that's what DID get for reusing a property definition that Mastodon
already squatted long before they got to it

8684964c5d Only allow exact id matches
This protects us from falling for obvious spoofs as from the current
upload exploit (unfortunately we can’t reasonably do anything about
spoofs with exact matches as was possible via emoji and proxy).

Such objects being invalid is supported by the spec, sepcifically
sections 3.1 and 3.2: https://www.w3.org/TR/activitypub/#obj-id

Anonymous objects are not relevant here (they can only exists within
parent objects iiuc) and neither is client-to-server or transient objects
(as those cannot be fetched in the first place).
This leaves us with the requirement for `id` to (a) exist and
(b) be a publicly dereferencable URI from the originating server.
This alone does not yet demand strict equivalence, but the spec then
further explains objects ought to be fetchable _via their ID_.
Meaning an object not retrievable via its ID, is invalid.

This reading is supported by the fact, e.g. GoToSocial (recently) and
Mastodon (for 6+ years) do already implement such strict ID checks,
additionally proving this doesn’t cause federation issues in practice.

However, apart from canonical IDs there can also be additional display
URLs. *omas first redirect those to their canonical location, but *keys
and Mastodon directly serve the AP representation without redirects.

Mastodon and GTS deal with this in two different ways,
but both constitute an effective countermeasure:
 - Mastodon:
   Unless it already is a known AP id, two fetches occur.
   The first fetch just reads the `id` property and then refetches from
   the id. The last fetch requires the returned id to exactly match the
   URL the content was fetched from. (This can be optimised by skipping
   the second fetch if it already matches)
   05eda8d193/app/helpers/jsonld_helper.rb (L168)
   63f0979799

 - GTS:
   Only does a single fetch and then checks if _either_ the id
   _or_ url property (which can be an object) match the original fetch
   URL. This relies on implementations always including their display URL
   as "url" if differing from the id. For actors this is true for all
   investigated implementations, for posts only Mastodon includes an
   "url", but it is also the only one with a differing display URL.
   2bafd7daf5 (diff-943bbb02c8ac74ac5dc5d20807e561dcdfaebdc3b62b10730f643a20ac23c24fR222)

Albeit Mastodon’s refetch offers higher compatibility with theoretical
implmentations using either multiple different display URL or not
denoting any of them as "url" at all, for now we chose to adopt a
GTS-like refetch-free approach to avoid additional implementation
concerns wrt to whether redirects should be allowed when fetching a
canonical AP id and potential for accidentally loosening some checks
(e.g. cross-domain refetches) for one of the fetches.
This may be reconsidered in the future.

3e134b07fa fetcher: return final URL after redirects from get_object
Since we reject cross-domain redirects, this doesn’t yet
make a difference, but it’s requried for stricter checking
subsequent commits will introduce.

To make sure (and in case we ever decide to reallow
cross-domain redirects) also use the final location
for containment and reachability checks.
