docs(runtime/dlp): real get-by-ID input/output examples (post SDK ^0.10.0)

[cdot65]

Summary

• Replaces aspirational ## get sections in patterns.md, profiles.md, filtering-profiles.md with real live-tenant input/output examples
• Drops the stale "upstream returns 400" warning on patterns + profiles (fixed by SDK ^0.10.0 / PR chore(deps): bump SDK to ^0.10.0 #212)
• Flags the remaining JSON snake_case mangling bug (DLP: filtering-profiles get JSON/YAML output mangles object keys #105) on profiles get and filtering-profiles get so users know to use pretty until that fix lands

Issues addressed

• Closes docs: runtime dlp patterns get (upstream-bug) #181 (patterns get) — now works end-to-end
• Updates docs: runtime dlp profiles get (upstream-bug) #184 (profiles get) — pretty works; JSON tracked under DLP: filtering-profiles get JSON/YAML output mangles object keys #105
• Updates docs: runtime dlp filtering-profiles get (CLI bug — partial) #188 (filtering-profiles get) — pretty works; JSON tracked under DLP: filtering-profiles get JSON/YAML output mangles object keys #105

Test plan

• Live-tested all three get commands against tenant 1852583913 with node dist/cli/index.js runtime dlp ...
• pnpm docs:check (124 commands, 30 allowlist)
