web: abstract rootInterface()?.config?.capabilities.includes() into .can() (#7737)

* This commit abstracts access to the object `rootInterface()?.config?` into a single accessor,
`authentikConfig`, that can be mixed into any AKElement object that requires access to it.

Since access to `rootInterface()?.config?` is _universally_ used for a single (and repetitive)
boolean check, a separate accessor has been provided that converts all calls of the form:

``` javascript
rootInterface()?.config?.capabilities.includes(CapabilitiesEnum.CanImpersonate)
```

into:

``` javascript
this.can(CapabilitiesEnum.CanImpersonate)
```

It does this via a Mixin, `WithCapabilitiesConfig`, which understands that these calls only make
sense in the context of a running, fully configured authentik instance, and that their purpose is to
inform authentik components of a user’s capabilities. The latter is why I don’t feel uncomfortable
turning a function call into a method; we should make it explicit that this is a relationship
between components.

The mixin has a single single field, `[WCC.capabilitiesConfig]`, where its association with the
upper-level configuration is made. If that syntax looks peculiar to you, good! I’ve used an explict
unique symbol as the field name; it is inaccessable an innumerable in the object list. The debugger
shows it only as:

    Symbol(): {
        cacheTimeout: 300
        cacheTimeoutFlows: 300
        cacheTimeoutPolicies: 300
        cacheTimeoutReputation: 300
        capabilities: (5) ['can_save_media', 'can_geo_ip', 'can_impersonate', 'can_debug', 'is_enterprise']
    }

Since you can’t reference it by identity, you can’t write to it. Until every browser supports actual
private fields, this is the best we can do; it does guarantee that field name collisions are
impossible, which is a win.

The mixin takes a second optional boolean; setting this to true will cause any web component using
the mixin to automatically schedule a re-render if the capabilities list changes.

The mixin is also generic; despite the "...into a Lit-Context" in the title, the internals of the
Mixin can be replaced with anything so long as the signature of `.can()` is preserved.

Because this work builds off the work I did to give the Sidebar access to the configuration without
ad-hoc retrieval or prop-drilling, it wasn’t necessary to create a new context for it. That will be
necessary for the following:

TODO:

``` javascript
rootInterface()?.uiConfig;
rootInterface()?.tenant;
me();
```

* web: Added a README with a description of the applications' "mental model," essentially an architectural description.

* web: prettier had opinions about the README

* web: Jens requested that subscription be  by default, and it's the right call.

- Also, removed redundant check.
