refactor(optimus-ui): avatar component migration to Signals API - #2074
Migrates p-avatar to the Signals API, following the angular-signal-migration guide and the earlier p-tag migration.
label, icon, image, size, shape, ariaLabel and ariaLabelledBy are now input(), with unchanged types and defaults. dataP is a computed().
onAfterViewChecked is replaced by afterEveryRender() in the constructor, and the redundant standalone: true is removed.
Removes the deprecated styleClass input; the native class attribute replaces it. The host class is now just cx('root').
Removes the unused $pcAvatar property and its private AVATAR_INSTANCE token.
Extends the styleclass-to-class schematic to cover p-avatar (selector list, migrations.json description, two new spec cases).
Rewrites the styleClass usages on <p-avatar> in apps/docs to class.
Updates avatar.test.ts for the signal API and adds an OnPush Rendering suite (one re-render test per input).
Adds src/avatar/MIGRATION.md with the consumer migration entries.

Breaking changes
styleClass removed from p-avatar. Use class / [class] instead. This is automated by the styleclass-to-class migration, which now covers p-avatar.
$pcAvatar removed. It was unused in the library and has no replacement.
Inputs are now signals. Template bindings are unchanged, but reading them from code needs a call, including inside pt callbacks that receive instance (for example instance.size(), not instance.size).
Full before/after usage is in packages/optimus-ui/src/avatar/MIGRATION.md.
The docs API generator (TypeDoc) picks up the signal inputs, but renders them as InputSignal<T> with a default of "...". That comes from the generator script and affects other migrated components too, so I left it out of this PR.
ESLint's config ignores these files, so lint wasn't a meaningful check and I didn't tick it.
Summary by CodeRabbit
Updates
Avatar inputs now use signal-based values; code reading them must call them to access their values.
Avatar custom styling now uses the native class attribute. The styleClass input and $pcAvatar access have been removed, with no direct replacements.
Avatar sizing and shape information is available as a computed signal.
Changes to Avatar inputs now update the rendered content, classes, and accessibility attributes.
Migration
The migration tool converts eligible Avatar styleClass attributes and bindings to class; some cases may need manual review.
Avatar migration guidance covers these changes and other breaking updates.
No actionable comments were generated in the recent review.
Walkthrough
Avatar now uses signal inputs and computed data for dataP. The change removes styleClass and $pcAvatar, extends the migration to p-avatar, and updates Avatar tests, migration documentation, and examples.

Summary
Signal inputs and rendering packages/optimus-ui/src/avatar/avatar.ts, packages/optimus-ui/src/avatar/style/avatarstyle.ts, packages/optimus-ui/src/avatar/avatar.test.ts
Avatar inputs now use signals, and dataP is computed from shape and size. Template and host bindings read signal values. Attribute binding uses afterEveryRender. Tests cover signal reads and OnPush rendering updates.
Migration tooling and guidance packages/optimus-ui/schematics/migrations.json, packages/optimus-ui/schematics/migrations/styleclass-to-class/migration.ts, packages/optimus-ui/schematics/test/styleclass-to-class.spec.ts, packages/optimus-ui/src/avatar/MIGRATION.md
The styleClass migration now includes p-avatar, with tests for static and bound attributes. The migration guide describes the API changes and cases requiring manual review.

Delete the usage; `Avatar` no longer exposes its parent avatar and there is no direct replacement. A component or directive placed inside an `Avatar` that needs the avatar instance can inject `PARENT_INSTANCE` from `@openng/optimus-ui/basecomponent` (without `skipSelf`), but this is not an equivalent of `$pcAvatar`, which pointed at an avatar enclosing another avatar. Usages are rare and need manual judgment, so this is not suited to an automated codemod.
- **Changed**: `label`, `icon`, `image`, `size`, `shape`, `ariaLabel` and `ariaLabelledBy` are now signal inputs. Template bindings (`[label]="x"`, `label="x"`) are unchanged, but reading them from code now requires a call, including inside `pt` callbacks that receive `instance`. `dataP` is now a `computed()`.

Document dataP() reads.
dataP is a public computed() signal, so code that previously read avatar.dataP must call avatar.dataP(). The current note only states that calls are required for the listed inputs. Add dataP to that sentence or show a before/after read.

Update the migration note to clarify that public computed signal dataP must be
read with a call, just like the listed signal inputs; include dataP in the
sentence describing code reads or add a before-and-after example.

- Line 9: Update the inline-template rewriting logic that uses
MIGRATED_SELECTORS to unwrap parenthesized initializers before checking for a
string template. Ensure templates such as parenthesized string literals are
rewritten or reported as conflicts, so the removed input cannot remain silently.
