fix(sync-jp-docs): improve translation coverage in angular and xplat workflows

[viktorkombov]

Summary

1. xplat: Added the missing Step 1b TOC filter (angular already had one).
   components/grids/_shared/ files are explicitly included — they are source
   templates expanded by generate.mjs and were translated in the legacy system.

2. Angular: Extended Step 1b to include grids_templates/ files.
   These are the canonical source for grid pages — generate-grids.mjs expands
   them at build time for every language including JP. The generated per-grid
   pages are git-ignored and never reach the diff; previously the TOC-only filter
   silently skipped the templates too, leaving them untranslated.

Note: This PR also regenerates the agentic workflow lock files and bumps
gh-aw tooling to v0.80.9. Review the lock file diffs for any unintended
behaviour changes beyond the TOC/template filtering updates above.

Checklist:

• check topic's TOC/menu and paragraph headings
• Include TOC topic labels in the topic content when it has a valuable update, is new, or is considered preview / beta
• link to other topics using ../relative/path.md
• at the References section at the end of the topic add links to topics, samples, etc
• reference API documentation instead of adding a section with API

• use valid component names - [Data] Grid, IgxSelectComponent, <igx-combo>
• use spell checker tool (VS Code, Grammarly, Microsoft Editor)
• add inline code blocks for the names of classes / tags / properties
• add language descriptor for the code blocks
• check if links function by running the check-api/mdx npm commands
• check if sample is working and fully visible in the topic
• check if sample is working and fully visible in the StackBlitz
• check if code blocks match the code in StackBlitz demo

• follow SEO guidelines to fill topic's metadata (SEO guidelines)

• do not resolve requested changes (leave that to the reviewer)

Pull request overview

Updates the JP sync agent workflows so more English documentation sources (including generated-template inputs) are considered “in-scope” for translation, improving translation coverage for both xplat and Angular docs.

Changes:

• xplat: add a Step 1b TOC-based filter and explicitly include components/grids/_shared/ MDX templates in the translatable set.
• Angular: extend Step 1b filtering to include grids_templates/ MDX sources and clarify the produced allowlist.
• Regenerate/upgrade agentic workflows tooling outputs (lock workflows, maintenance workflow) and adjust merge strategy for generated lock workflows.
