Closes https://github.com/PostgREST/postgrest/issues/4226.
This requires moving query generation to the top App.hs module.
At this point is also simple to log the transaction variables + the
pre-request function call but this is not done here to reduce scope.
The IPv6 address logged at the startup like `::1:80` was
wrong because the port isn't clearly separated. This commit
corrects it, now logging as `[::1]:80`.
This is done in accordance to RFC 3986. In short, we did this
have a clear separation between the port and host because
the components of an IPv6 are separated with the ':' character.

The prometheus metrics text format requires `Content-Type` header
for correct scraping which fails otherwise. Closes#4271.

Closes https://github.com/PostgREST/postgrest/issues/4245.
It adds a query on schema cache construction, but doesn't add a new
attribute to the SchemaCache type. We only need the information to be
passed to the `initialMediaHandlers` function to build the builtin media
handlers.
Changes:
1. Refactoring and some cleanup of JWT handling code:
* Instead of caching AuthResult cache decoded claims (which signature was verified). Validating claims and determining role is done after cache lookup
* Cleaned up API so that usage of it is simplified: lookupJwtCache cache key >>= parseClaims configJwtAud time
* Handling of JwtCacheState initialization and updates of configuration is encapsulated in Auth.JwtCache module
2. Generic high performance (hopefully) scalable, dynamically resizeable cache implementation based on stm, stm-hamt and sieve algorithm. It also integrates with PostgREST measurements infrastructure providing usage stats (ie. hit ratio, evictions count)
The OpenAPI specification was incorrectly exposing GET methods for
VOLATILE functions, even though such functions properly reject GET
requests at runtime with "405 Method Not Allowed". This created
a mismatch between the advertised API specification and the actual
runtime behavior.
VOLATILE functions should only be callable via POST since they may
have side effects, while STABLE and IMMUTABLE functions can safely
be called via GET since they don't modify database state.
Fix by checking the pdVolatility field in makeProcPathItem() and
only including GET methods in the OpenAPI PathItem for non-volatile
functions.
The runtime behavior was already correct; this fixes only the
OpenAPI documentation generation.
The `jwt-aud` config was not validated when containing ':'
character according to RFC 3986. This fix validates it and
fails at startup if it is invalid.
BREAKING CHANGE
The endpoint was at risk of being left unprotected when exposing it.
The accompanying `admin-server-config-enabled` config was also dropped.
