feat(admin): extract shared settings-config module for CLI and admin UI

[Ferryx349]

Description

Extracts settings read/validate/path logic from src/cli/utils/config.ts into shared runtime modules so the admin settings editor (Phase 3) can reuse the same primitives as the CLI.
Also exports the guided field schema from the configure TUI for admin UI consumption.

Why

The admin console settings editor needs the same dot-path get/set, validation, and guided field metadata that the CLI already uses. Duplicating that logic would drift over time; this PR establishes a single source of truth ahead of the admin UI work.

Pull request overview

This PR extracts the CLI’s settings configuration primitives (settings file paths, load/save, dot-path get/set, and validation) into shared runtime modules under src/utils, so both the CLI and the upcoming admin settings editor can reuse the same implementation. It also exports the guided settings schema previously embedded in the CLI configure TUI.

Changes:

• Introduces shared src/utils/settings-config.ts (settings IO, dot-path helpers, validation) and src/utils/settings-guided-schema.ts (guided field metadata + validators).
• Updates CLI commands/TUI to consume the shared modules (and turns the old CLI config module into a re-export shim).
• Adds unit tests for the extracted settings-config and guided schema modules, plus a changeset.
