Feature: UX improvements (blueprint search, sortable list, and more)

[macpit]

Original issue: Sian-Lee-SA#401

Requested Improvements (sorted by effort)

1. Blueprint search — Add a search field to the blueprint selector dialog (Low, ~4h)
2. Sortable switch list — Add sortable columns to the main switch list (Low, ~4h)
3. Default switch name — Auto-fill from HA device name (Low-Medium, ~4-6h)
4. Switch name at end of setup — Move naming to the end of the wizard flow (Medium, ~6-8h)
5. Rename/hide blueprints — Needs storage for user overrides (Medium-High, ~8-12h)
6. Type selection in discovery — Wizard rewrite (High, ~12-16h)

Plan

Items 1-2 are quick wins and will be tackled first. Items 3-6 are on the backlog.

Effort

High (total 30-60h for all items)

Migrated from original repo

[macpit]

Sortable switch list (item 2) is done in v3.0.5.

Enabled sorting on the Name, Service, and Type columns in the switch list data table. Click a column header to sort ascending, click again for descending.

Fixed a bug in the sm-data-table wrapper where sorting never worked because it referenced this._sortColumn (internal, never set) instead of this.sortColumn (set by the parent's header click handler).

Remaining items (blueprint search, default switch name, etc.) are still open.
