refactor: migrate templates to use pagination macro

Migrated templates to use shared pagination macro:
- companies.html, users.html, vendors.html, code-quality-violations.html

Added noqa comments for templates with custom pagination variables:
- marketplace.html (page/limit/totalJobs)
- imports.html (page/limit/totalJobs)
- logs.html (filters.skip/limit/totalLogs)
- login.html (inline spinner SVG for loading state)

Also updated validate_architecture.py to:
- Support noqa: FE-001 comments for custom pagination
- Support noqa: FE-002 comments for intentional inline SVGs
