Feature: Add Missing Core Jinja2 Template Snippets

[EndlessTrax]

Problem

Common macro import tags and filter blocks are missing from jinja-snippets.json.

Solution

Add the following snippets to snippets/jinja-snippets.json:

• ptj-imp ({% import 'file.html' as name %}): For importing macros.
• ptj-from ({% from 'file.html' import macro %}): For importing specific macro.
• ptj-raw ({% raw %}...{% endraw %}): Escapes Jinja rendering for JS frameworks.
• ptj-fil ({% filter name %}...{% endfilter %}): Block filter.
