Oleg Isonenandshreyanshkotak 81bae6339b feat: page templates (#5785) ...

## Description

1. Issue: https://github.com/webstudio-is/webstudio/issues/4931
2. Adds V1 of Page Templates for designers:
   - stores project-local page templates separately from published pages
   - adds a designer-only Page Templates section in the Pages panel
- supports creating, editing, duplicating, deleting, and reordering
templates
- supports creating a regular page from a template through a prefilled
page settings dialog
- makes canvas/page awareness, asset usage, asset replacement, and
page-copy utilities template-aware while keeping templates out of normal
public page lookup paths

## Steps for reproduction

1. Open the builder in Design mode and open the Pages panel.
2. Click the New Template button in the Page Templates section.
3. Fill in template settings, including name, title, description, search
toggle, social image, and custom metadata.
4. Click Create template and expect the new template to appear under
Page Templates and load on the canvas with an editable blank body.
5. Add content to the template canvas, reopen template settings, change
metadata, close/reopen settings, and expect the changes to persist.
6. Click the `+` action on the template row and expect a Create Page
from Template dialog prefilled from the template with a unique page
path.
7. Change page settings, click Create page, and expect a normal page to
be created in the root folder with copied content and metadata while the
template remains unchanged.
8. Right-click a template row, choose Duplicate, and expect a new
independent template copy with a deduplicated name.
9. Drag templates within the Page Templates section and expect the order
to persist.
10. Right-click a template row, choose Delete, confirm deletion, and
expect the template and its canvas tree to be removed. If the deleted
template was selected, expect the builder to navigate back to the home
page.
11. Switch to Content mode and expect template management UI to be
hidden.
12. Use a template social image from Assets, check asset usages, replace
the asset, and expect the template social image reference to update.

## Code Review

- [ ] hi @kof, I need you to do
  - conceptual review (architecture, feature-correctness)
  - detailed review (read every line)
  - test it on preview

## Before requesting a review

- [x] made a self-review
- [x] added inline comments where things may be not obvious (the "why",
not "what")

## Before merging

- [x] tested locally and on preview environment (preview dev login:
0000)
- [ ] updated [test
cases](https://github.com/webstudio-is/webstudio/blob/main/apps/builder/docs/test-cases.md)
document
- [ ] added tests
- [ ] if any new env variables are added, added them to `.env` file
