[Registrar] Rewrite transfer page and add registration limits troubleshooting

[mhsu]

Rewrites the "Transfer your domain to Cloudflare" page for clarity and adds registration limits content to the troubleshooting page. Follows up on #28723 (merged).

Transfer page (transfer-domain-to-cloudflare.mdx):

• Restructured from a flat 10-step list into two clear phases: (1) Add your domain to Cloudflare, (2) Transfer your registration — so users understand they cannot just paste an auth code like other registrars
• Inlined content from three partials (requirements, before-you-begin, restrictions) that were only used on this page
• Added DNSSEC provider links and nameserver change links in collapsible Details blocks
• Explained why each step is needed (DNSSEC causes resolution failures, zone must be Active before auth code entry, etc.)
• Added "Registration limits and the one-year extension" Details block with max periods (10 years for most TLDs, 5 for .co), rejection reasons, TLD-specific requirements (.ai 2-year minimum, .uk no extra year), and concrete actionable guidance with examples
• Replaced vague language throughout: specific ICANN contact-change lock fields (name, organization, email), concrete 45-day expiration rule instead of "may result", specific WHOIS status explanations
• Added website builder callout near the top linking to the workaround section
• Changed pcx_content_type from tutorial to how-to

Troubleshooting page (troubleshooting.mdx):

• Added new "Transfer rejected due to registration limits" section with max registration periods, common rejection reasons, and what users can do (with concrete example: .com with 9.5 years must wait 6 months)
• Expanded "Domain is in a restricted status" from a single vague sentence to per-status explanations (clientHold/serverHold = suspended, redemptionPeriod = expired past grace, pendingDelete = scheduled for deletion)

Preserves all existing anchors referenced by external pages: #disable-dnssec, #transfer-from-website-builders, #restrictions.

/bonk review this PR for duplicative content and other potential issues

Agreeing with most of kodster28's feedback. Posting additional items below — 1 medium issue (missing partial content), 2 low issues, plus suggestions addressing some of the prior review comments.

The restructuring into two clear phases is a good approach, and the troubleshooting additions are solid. The anchor preservation (#disable-dnssec, #transfer-from-website-builders, #restrictions) checks out.

Note: The email-verification partial (Render file="email-verification" product="registrar") was removed in this rewrite. It warned users with unverified account emails that they cannot transfer or register domains. Consider adding that note back — either inline or in the "Before you begin" Details block.

Review submitted. Here is what I posted:

Summary: 9 inline comments with suggestions, plus a top-level note about the removed email-verification partial.

Key items:

• MEDIUM: The DNSSEC provider list (lines 67-82) should use the existing <Render file="dnssec-providers" product="dns" /> partial instead of a hand-maintained subset. The partial has 12+ more registrar links and is shared across 6 pages.
• LOW: "Block" on line 17 — unclear if this means "Bluehost" or another platform.
• LOW: "internationalized domain name (IDN)" on line 31 needs a brief clarification for non-technical users.
• Note: The email-verification partial was dropped — it warned users with unverified emails that they cannot transfer domains. Should be added back to the "Before you begin" block.

I also posted suggestions reinforcing kodster28's prior feedback (opening paragraph density, leading with actions, cross-linking instead of repeating content, and linking "active on Cloudflare" to the full-setup docs).
