billing: remove deprecated Remote MCP references

[micheleRP]

Description

Resolves: no linked issue — incidental cleanup of pages missed by #562 (Remove deprecated ADP content) and b4b87469 (Remove deprecated Remote MCP documentation).
Review deadline: none

Removes the == Remote MCP billing metrics section from the Billing page and strips incidental Remote MCP mentions from the Manage payment methods and View billing activity pages.

📝 Walkthrough

Walkthrough

This pull request updates billing documentation across three Asciidoc pages to modify Remote MCP references. The main billing page removes the entire "Remote MCP billing metrics" section, causing the "Support plans" section to follow directly after the "Redpanda Connect billing metrics" table. The payment methods page removes "Remote MCP servers" from the list of billable resources covered by credit cards. The billing activity page adds "Remote MCP server" to the described resources included in the per-resource cost breakdown.

PR Review: billing: remove deprecated Remote MCP references (#595)

Files reviewed: 3 .adoc files (2 additions / 21 deletions)
Overall assessment: Clean, minimal deletion-only cleanup. No issues. Safe to merge.

What this PR does

Removes residual mentions of the deprecated "Remote MCP" feature from three cloud-docs billing pages that earlier cleanup work (#562 and commit b4b87469) missed:

• billing.adoc: drops the entire == Remote MCP billing metrics section (19 lines).
• manage-payment-methods.adoc: strips ", Remote MCP servers" from one inline list.
• view-billing-activity.adoc: strips ", Remote MCP server" from one inline list.

This brings the billing pages in line with the already-announced deprecation in whats-new-cloud.adoc (April 2026, "Remote MCP: Deprecated").

Jira ticket alignment

Ticket: None — PR body explicitly states "no linked issue — incidental cleanup of pages missed by #562 and b4b87469." Treated as housekeeping; no ticket needed.

Critical issues (must fix)

None.

Suggestions (should consider)

None of substance. The diff is correct, minimal, and removes only what should be removed.

Impact on other files

• No incoming xrefs: grep across modules/ finds zero references to a #remote-mcp-billing-metrics anchor or "Remote MCP billing" content anywhere in cloud-docs. The removal won't break any cross-references.
• No leftover "Remote MCP" mentions elsewhere in cloud-docs except the intentional deprecation announcement at modules/get-started/pages/whats-new-cloud.adoc:44–46. That's the correct place for it to stay — it's announcing the deprecation, not promoting the feature.
• No nav.adoc update needed — no pages added/removed/renamed, just intra-page deletions.
• No What's New update needed — the deprecation was already announced in the April 2026 section.
• No cross-repo (single-source) risk — modules/billing/ is cloud-only, not single-sourced from redpanda-data/docs.

CodeRabbit findings worth considering

None. CodeRabbit's check passed with no review summary or comments to triage.

What works well

• Clean Oxford-comma list rewrites. Both inline-list edits leave the surrounding sentence well-formed — "Serverless, Dedicated, and BYOC clusters, Redpanda Connect pipelines, and your support plan" reads naturally with no orphan commas.
• Scope is tight. The PR removes only Remote MCP references in billing/, doesn't touch the intentional deprecation announcement, doesn't try to fold in other unrelated cleanups.
• PR body is informative. Cross-references the prior cleanup PR (#562) and commit (b4b87469) so reviewers (and future archaeologists) have the deprecation provenance.
• CI is green and the diff is small enough that the Netlify preview links in the PR body cover all three changed pages.
