Stefan Agner 0f881d69fe Model client-state Apps* errors as APIError (#6856)
* apps: model client-state Apps* errors as APIError

Follow-up on #6739: with HassioError now logged and captured by Sentry
in api_process, a handful of Apps* exceptions raised from
AppManager.install/update/rebuild and AppModel._validate_availability
surfaced as "unexpected" 400s with a noisy log entry and a Sentry
event, even though they are all user/client-state errors (clicked
install on an already-installed add-on, "no update available", local
and store versions diverged, system architecture/machine/HA version
incompatible, etc.). The dominant offender is SUPERVISOR-1JVV
("No update available for app core_mosquitto", ~19k events / ~12k
users), but several siblings show the same shape.

Map these through properly so the API returns clean, structured 400s:

- Add modeled APIError subclasses in exceptions.py for the previously
  raw raises in apps/manager.py: AppAlreadyInstalledError,
  AppNotFoundError, AppNotInstalledError, AppNotInStoreError,
  AppNoUpdateAvailableError, AppRebuildVersionChangedError,
  AppRebuildImageBasedError. Each gets a stable error_key, a
  message_template, and an "addon" extra_field.
- Add APIError to AppNotSupportedArchitectureError,
  AppNotSupportedMachineTypeError and
  AppNotSupportedHomeAssistantVersionError so they behave the same as
  the other Apps* APIErrors instead of being treated as unexpected.
- Pass the app's display name (app.name from the add-on config)
  instead of the slug to extra_fields wherever an App or AppModel is
  available at the raise site, so users see "Mosquitto broker" rather
  than "core_mosquitto" in error messages. Slug is only used as a
  fallback when no app object exists (install of an unknown slug,
  update/rebuild of a slug that is not installed).
- Update raise sites in apps/manager.py and apps/model.py to use the
  new typed exceptions and the addon= keyword.

These are all runtime states users hit during normal interaction with
the apps UI, not Supervisor bugs worth paging on.

* apps: include slug alongside name in Apps* APIError extra_fields

Address review feedback from #6856: clients still need the slug to look
up additional add-on information (the name is for display only), and we
should be consistent about it across the Apps* errors touched by this
PR.

Every Apps* APIError raised with an App/AppModel available now carries
both `addon` (display name, used by the message_template) and `slug` in
extra_fields. Raise sites in apps/manager.py and apps/model.py pass
both. The two errors raised before an app object exists keep slug-only
extra_fields and use {slug} in their message:

- AppNotFoundError (install of an unknown slug)
- AppNotInstalledError (update/rebuild of a slug not in self.local)

Pre-existing Apps* APIErrors outside the scope of this PR
(AppUnknownError, AppConfigurationInvalidError, AppBootConfigCannot
ChangeError, AppNotRunningError, AppPortConflict, AppNotSupportedWrite
StdinError, AppBuild*) will be migrated in a follow-up.

* apps: introduce AppAPIError base for uniform addon/slug extra_fields

Address review follow-up on #6856: the addon/slug convention was
enforced only by hand-rolled __init__s, easy to drift on (forget slug,
use a different key, etc.). Promote it to a base class that owns the
shape of extra_fields for all App-related API errors.

- Add AppAPIError(AppsError, APIError). Its __init__ takes
  `app: AppModel | App | AppStore | str` and uniformly populates
  extra_fields with `addon` (display name) and `slug`. Pass a string
  when no app object exists; only `slug` is set in that case. Extra
  per-error fields flow through **extra_fields and merge with the
  defaults.
- Convert the new exceptions added in this PR
  (AppAlreadyInstalledError, AppNotFoundError, AppNotInstalledError,
  AppNotInStoreError, AppNoUpdateAvailableError,
  AppRebuildVersionChangedError) into thin subclasses that only declare
  error_key and message_template -- the __init__ is inherited.
- Migrate the AppNotSupported* errors (architecture, machine type, HA
  version) and AppRebuildImageBasedError to use AppAPIError too;
  their bespoke per-error fields go through **extra_fields. They keep
  inheriting AppNotSupportedError so `except AppNotSupportedError`
  callers (e.g., AppModel._available) still work; MRO routes __init__
  through AppAPIError.
- Update raise sites in apps/manager.py and apps/model.py to pass
  `app=<obj-or-slug>` instead of repeating `addon=...` and `slug=...`.

Pre-existing App* APIErrors outside this PR's scope
(AppUnknownError, AppConfigurationInvalidError,
AppBootConfigCannotChangeError, AppNotRunningError, AppPortConflict,
AppNotSupportedWriteStdinError, AppBuild*) will be migrated to
AppAPIError in a follow-up; the base class is in place for them.

* apps: tighten AppAPIError model per review

Address mdegat01's two follow-ups on #6856 (review approved as-is,
this is the cleanup):

- AppNotFoundError and AppNotInstalledError are raised before any
  App/AppModel object exists (unknown slug; not-installed slug). Pull
  them out of AppAPIError and inherit (AppsError, APIError) directly
  with a slug-only __init__ + {slug} message_template. Removes the
  conceptually-wrong str branch from AppAPIError.__init__: it now
  strictly requires an app-like object with .name and .slug.
- Restore per-class typed __init__ on AppNotSupportedArchitectureError,
  AppNotSupportedMachineTypeError and
  AppNotSupportedHomeAssistantVersionError so callers get an explicit
  signature for the bespoke architectures/machine_types/version params
  instead of dumping them through **extra_fields. Each override just
  delegates to AppAPIError.__init__, which keeps ownership of the
  addon/slug shape. The list-joining for architectures/machine_types
  moves back into the override (raise sites pass the raw list again).

AppRebuildImageBasedError takes no bespoke fields and stays a plain
AppAPIError subclass.
