fix(terraform_plan): apply inline skip comments when deep analysis is enabled

Description

RunnerRegistry._handle_report gated the whole plan enrichment block on deep analysis being off, and that block is the only place where inline checkov:skip comments get applied to plan scans. Running --repo-root-for-plan-enrichment together with --deep-analysis therefore dropped every inline suppression, while the same scan without --deep-analysis honored them.

This change parses the enrichment repo root and applies Report.handle_skipped_checks in both modes. The file path, line range and code block rewriting of Report.enrich_plan_report stays on the non-deep path, because deep analysis reports records against the plan file through the merged graph and existing tests pin that behavior.

The new test mirrors the existing test_skip_check with deep_analysis=True and fails without the fix.

Fixes #7643 (previously reported in #6815 and #7225, both closed by the stale bot without a fix)
