4grayandClaude Opus 5.5 8d01ae5f75 perf(web): provide form-field defaults per component, not at the root
app.config.ts provided MAT_FORM_FIELD_DEFAULT_OPTIONS in the root
injector. Importing the token kept @angular/material/form-field in
main.js, and Material 22.2's form field imports @angular/forms/signals,
which would add @angular/forms to startup as well (the reason the
Angular 22.2 dependency update exceeds the initial-bytes ratchet). Every
form field renders in a lazy chunk, so the outline + dynamic defaults
now come from provideFormFieldDefaults()
(@iptvnator/ui/components/form-field-defaults) on each component that
renders <mat-form-field>.

tools/nx/check-form-field-defaults.mjs (ui:form-field-defaults:validate,
run in CI) reports a component that renders a form field without the
provider, and any use of the token outside the shared provider. The
Xtream import form test asserts outlined, dynamically sized fields with
no root provider; without the component provider they render as fill.

renderer.initialBytes: 1,596,201 -> 1,534,604 bytes (-61,597) on a local
production build; the baseline is lowered to the measured value.
