Cross-app id: the frontend still hardcodes old app ids (404 on half the fleet)

[rubenvdlinde]

The PHP half of the cross-app id fix is shipping (openregister #2867, learniq #616, pipelinq #1437, shillinq #1252) via a FleetAppId resolver that picks the id the instance actually registered from a newest-first list.

The frontend half is not fixed, because JavaScript cannot ask IAppManager.

Remaining hardcoded sites

app	file	pinned path
launchpad	src/services/spendAnalytics.js:218	/apps/openconnector/api/sources/{source}/call
pipelinq	src/main.js:218	/apps/openbuild/api/app-overrides/pipelinq
pipelinq	src/App.vue:203	/apps/openbuild/api/app-overrides/pipelinq
learniq	src/App.vue:18-19	/apps/openconnector/api/lti/..., /apps/openconnector/api/payments/...

Why it matters

A URL segment is a routing key — Nextcloud mounts routes under the registered app id. development has completed the rename (integriq, buildiq), while beta and main still register the old ids. So each of these paths is a 404 on half the fleet, and a 404 from a background fetch is not something anyone sees.

Suggested fix

The PHP side already knows the answer. Provide it to the frontend rather than duplicating the map in JS:

// in the app's PageController / Application bootstrap
$this->initialState->provideInitialState(
    'fleetAppIds',
    [
        'integriq' => FleetAppId::resolve($this->appManager, 'integriq'),
        'buildiq'  => FleetAppId::resolve($this->appManager, 'buildiq'),
    ]
);

import { loadState } from '@nextcloud/initial-state'
const ids = loadState('<app>', 'fleetAppIds', {})
const url = generateUrl(`/apps/${ids.integriq ?? 'integriq'}/api/sources/{source}/call`, { source })

That keeps a single source of truth (appinfo/info.xml → FleetAppId → initial state) and degrades to the canonical id if the state is absent.

Not in scope

• OpenRegister register slugs stay frozen — they are literals already written into stored data.
• Docblock/comment mentions of old ids are not executable and need no change.

Once beta and main carry the new ids everywhere, FleetAppId and this plumbing should both be deleted — they are transitional shims, not architecture.
