* feat(lib/policy): add support for CEL checkers
This adds the ability for administrators to use Common Expression
Language[0] (CEL) for more advanced check logic than Anubis previously
offered.
These can be as simple as:
```yaml
- name: allow-api-routes
action: ALLOW
expression:
and:
- '!(method == "HEAD" || method == "GET")'
- path.startsWith("/api/")
```
or get as complicated as:
```yaml
- name: allow-git-clients
action: ALLOW
expression:
and:
- userAgent.startsWith("git/") || userAgent.contains("libgit") || userAgent.startsWith("go-git") || userAgent.startsWith("JGit/") || userAgent.startsWith("JGit-")
- >
"Git-Protocol" in headers && headers["Git-Protocol"] == "version=2"
```
Internally these are compiled and evaluated with cel-go[1]. This also
leaves room for extensibility should that be desired in the future. This
will intersect with #338 and eventually intersect with TLS fingerprints
as in #337.

* Add check endpoint which can be used with nginx' auth_request function
* feat(cmd): allow configuring redirect domains
* test: add test environment for the nginx_auth PR
This is a full local setup of the nginx_auth PR including HTTPS so that
it's easier to validate in isolation.
This requires an install of k3s (https://k3s.io) with traefik set to
listen on localhost. This will be amended in the future but for now this
works enough to ship it.

Moves the Open Graph (OG) tags from the index template to

BaseWithOGTags function to the web package to allow
passing OG tags to the base template. Removes the
ogTags parameter from the Index function and template.

* feat(og-tags): Remove og-query-distinct flag
This commit removes the `og-query-distinct` flag and
associated logic. URLs with different query parameters
will now always be treated as the same cache key for Open
Graph tags. This simplifies the caching logic and
improves performance.
Additionally, the http client used for fetching OG tags
is now a member of the OGTagCache struct, rather than a
global variable. This improves testability and allows
for more flexible configuration in the future.
