Traffic policies: reference pages, TLS decryption section, Send traffic to Gateway

[mahathi-hariharan]

Supplemental 1- reference + TLS + Send traffic

Summary

Continues the Traffic policies reorg (builds on #32051):

• Reference pages grouped under reference/: application-app-types,
  domain-categories, global-policies, identity-selectors, order-of-enforcement,
  and expression-syntax → reference/policy-expressions. Adds a reference/ overview.
• TLS decryption elevated to its own top-level section (tls-decryption/, incl.
  HTTP/3 inspection), moved out from under HTTP policies.
• Proxy → Send traffic to Gateway: proxy.mdx reworked into a send-traffic-to-gateway.mdx
  page enumerating on-ramps with current product names; overview refreshed.

Redirects

301 redirects for all moved URLs (TLS redirects ordered before the http-policies/*
wildcard so they resolve directly — no chains). Validated with bin/validate-redirects.ts.

#### CV-a3bc48c82d0e · PR title format
- **File:** PR-level finding
- **Issue:** The title "Reorg send traffic" does not identify the affected product or docs area, so a reader cannot tell it concerns Cloudflare One/Gateway traffic policies.
- **Fix:** Prefix the title with the product or area, e.g. "[Cloudflare One] Reorganize Gateway traffic on-ramp docs".

#### CV-277d0c460da2 · Scope accuracy
- **File:** PR-level finding
- **Issue:** The description explains three areas of the reorg (reference pages, TLS decryption, proxy/send-traffic page), but the changed files include extensive modifications across many other products and sections (AI Gateway, BYOIP, Network Firewall, Access, DLP, Insights, integrations, networks, Remote Browser Isolation, and numerous changelog entries) that are not mentioned.
- **Fix:** Add a note accounting for the broad cross-product link/reference updates caused by the reorganization.
