fix: disable fof/redis settings cache to avoid circular boot dependency (#7)

fof/redis >=1.1 introduces a `settings` service that replaces
SettingsRepositoryInterface with a Redis-backed caching layer.
Enabling it here creates a circular dependency: this extension reads
settings to decide which Redis services to enable, but with the
settings cache active those reads require Redis to already be wired.

Always disable the `settings` service when delegating to fof/redis.
Also fixes a cast-precedence bug in the database env var helpers
where `(int) getenv(...) ? getenv(...) : N` applied the cast to the
ternary condition rather than the result, causing REDIS_DATABASE_*=0
to return the default instead of 0.

+## Compatibility with `fof/redis`
+
+This extension depends on [`fof/redis`](https://github.com/FriendsOfFlarum/redis) and deliberately disables the **`settings` service** that `fof/redis` ≥ 1.1 provides.
+
+`fof/redis`'s settings service replaces Flarum's `SettingsRepositoryInterface` with a Redis-backed caching layer. However, this extension reads settings (e.g. which Redis services to enable) during its own boot sequence — *before* Redis is fully wired into the container. Enabling the Redis settings cache here would create a circular dependency: configuring Redis requires reading settings, but reading settings requires Redis.
+
+The `settings` service from `fof/redis` is therefore always disabled in this extension's extender. If you want Redis-backed settings caching, configure `fof/redis` directly in your project's root `extend.php` instead of using this extension.
