Convert `MetadataHandler` to an abstract base class and add an
`is_enabled` class method that allows every metadata handler to
independently report whether it is enabled based on its configuration.
This avoids the need for global variables in the config module, allowing
us to change the enabled state of a metadata handler at runtime if
needed.
The `emoji` library has been removed, in favor of using constants for
the few emojis used in the codebase. This reduces memory usage, and
avoids calling `emojize` for Python to discover where to replace emojis
in pre-defined strings.
The previous function name `get_matched_roms_by_id` was misleading as it
returned a list of matched ROMs, but searching by ID should always
return either one result or none.
Instead of using just strings, this change converts the scopes to a
`StrEnum`, to be compatible with places where a string is expected. This
avoids typos when using these scopes, simplifies searching for usages,
and improves type hints.
An extra change was the fix to the Firmware download endpoint, which
wasn't respecting the `DISABLE_DOWNLOAD_ENDPOINT_AUTH` flag.
According to multiple FastAPI discussions [1], FastAPI only includes a
built-in mechanism to redirect requests including a trailing slash, to
its variation without slash, using a `307` status code.
This can be an issue when certain clients do not send the same headers
on the redirected request.
This change adds a custom FastAPI `APIRouter`, that registers both route
path variations (with and without trailing slash), while only marking
the path without slash for being included in the OpenAPI schema.

Convert `IGDBBaseHandler` methods to be asynchronous, and use an `httpx`
async client, instead of `requests` sync client.
This change also removes the direct dependency with `requests`, as the
project no longer uses it, preferring `httpx` instead.
