docs(kanvas): document Help and Support provider and identity preconditions

[leecalcote]

Description

Documents the Kanvas Help & Support behavior changes shipped in layer5labs/meshery-extensions#4321 (released v1.0.65-2), where support submissions moved from a browser-to-third-party-webhook POST to a Meshery-Server-relayed path (browser -> Meshery Server extension proxy -> Cloud WEBHOOK_HELP_AND_SUPPORT).

Three user-visible consequences, each now findable by a user who hits it:

1. Help and Support requires a remote provider. The submission traverses Meshery Server's extension proxy, which returns not-implemented under the local provider. New page content/en/kanvas/reference/help-and-support.md states this alongside the other Cloud-bound Kanvas features that share the constraint, with remediation.
2. The form requires a resolved signed-in identity. The profile is fetched when the dialog opens (loading state shown); if it cannot be resolved the form is withheld and nothing is submitted. Same page, with remediation.
3. Self-hosted addendum. content/en/cloud/guides/self-hosted/customizing-webhooks.md gains a note that WEBHOOK_HELP_AND_SUPPORT now also receives Kanvas-originated tickets, with the same memberFormOne payload shape, so no webhook-side change is needed.

Also cross-linked from Troubleshooting Kanvas, since Kanvas's Get Help action opens this form.

Out of scope drive-by: the webhook guide skipped from "Step 2" to "Step 4"; renumbered, and tidied the Step 1 wording.

Text-only; no fabricated screenshots. hugo builds clean locally.

Fixes #1192

Warning

Review limit reached

@leecalcote, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 56 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
