fix(apache): scope NE rewrite flag to API routes

[rajanpanth]

Summary

• keep NE only on a dedicated API rewrite rule (^/api/v[0-9]+/.*) to preserve encoded API paths
• remove NE from the general workhorse proxy rewrite so whitespace paths are rewritten safely
• apply the same change consistently across all Apache 2.2/2.4 + SSL/omnibus recipe variants

Why

Issue #304 reports 400 errors for paths containing whitespace when the global proxy rewrite uses NE.
This restores the earlier split behavior (API paths keep NE, general paths do not), so both use-cases are covered.

Validation

• deterministic pattern check confirms all 8 Apache recipe files now contain:
  • one API-specific NE rewrite
  • one general non-NE rewrite
