App-title and language sit in one App identity card now (both single-field
sections; separate cards were chrome-heavy). The trivial info blockquotes
that paraphrased the field labels are gone, and the per-field descriptions
on the user creation defaults dropped because the section blockquote
already says when the values apply. The "User creation rules" label is
renamed to "User creation defaults" so the card title matches its scope.

Splits the 755-line monolithic settings page into a tile-based landing hub
and six focused subpages (general, security, email, api, sso, branding),
each with its own form, CSRF scope and POST handler. Each subpage offers
Save / Save & close buttons plus a Cancel/back link to the hub.
Backend (AdminSettingsService, gateways, policies, DB schema) unchanged.
A new settingsSectionMergePost() helper overlays section POSTs onto the
current DB values so partial saves don't wipe unrelated fields (the
service defaults missing keys to 0/empty).
Sub-action files (logo/favicon/tokens/lifecycle) redirect to the matching
subpage, and architecture contracts now check the subpage files instead
of the removed monolithic index.
