TopSkills Experts V1.5 update package

Purpose:
- Cumulative cPanel upload package for the TopSkills Experts Candidate Finder customization.
- Keeps the original recruitment portal as the core.
- Adds ATS Resume Builder, Admin Plugins, demo management, PWA shell, IP tracking, and HRM plugin preview files.
- Fixes database import by adding an import-safe SQL dump with table drops and foreign-key checks disabled during restore.
- Fixes `/data` importer timestamp mismatch on `cf_industries`.
- Hardens candidate DataTables endpoints against older databases missing `account_type`.
- Refreshes the beta landing hero with clearer CTAs, stronger SaaS positioning, and modernized module cards.

Upload notes:
- Do not replace the live `.env`.
- Do not remove the live `vendor/` folder.
- Keep existing `storage/uploads` files.
- After upload, open `/schema` once, then `/admin/plugins`.
- Run `/data` only when you intentionally want to seed demo/sample content.
- For database restore, import `sabetiay_topskills.sql` or `database/sabetiay_topskills_import_safe.sql`.
- The import-safe SQL replaces existing tables. Back up the target database first.

Important new routes:
- `/admin/plugins`
- `/account/ats-resume-builder`
- `/{employer-slug}/account/ats-resume-builder`
- `/demo/request`
- `/admin/demo-requests`
- `/admin/hr-suite`
