perf(nextjs): fewer identity-server requests per server render

[DonOmalVindula]

Problem

AsgardeoServerProvider runs on every server render of the layout and, for a signed-in user, made six requests to the identity server each time: SCIM2 Me and Schemas twice (getUserAction and getUserProfileAction each fetch both), the user's organizations, and the branding preference, which was never cached and always requested for en-US. The React SDK does this work once per app load.

Fix

• The user is derived from the profile response (generateUserProfile(profile, schemas), exactly what getUser() computes; when the profile fell back to the ID token claims, those are used directly). This removes two SCIM2 requests per render.
• The branding preference is cached in memory (withBrandingPreferenceCache) for five minutes per base URL, type, name and locale. Concurrent renders share the in-flight request and a failed fetch is not cached, so the next render retries.
• The branding request uses the configured preferences.i18n.language (falling back to en-US), and failures go through the SDK logger instead of console.warn.

Not changed here: the default of fetching the branding (inheritFromBranding !== false) differs from the React SDK (=== true), but flipping it would silently remove branding from existing Next.js apps, so it is left as is.

Testing

• New cache unit tests (dedupe within TTL, reload after TTL, separate keys, failures not cached) and a caching test on the action; 65 tests pass.
• pnpm lint and tsc --noEmit for @asgardeo/nextjs.
