v27: Harden ENSJobPages preview and add FreeTrialSubdomainRegistrar alpha-agent mint flow

[MontrealAI]

Motivation

• Finish and harden the ENS Job Page preview so displayed values come from the live AGIJobManager.ensJobPages() path and show a clear degraded fallback when unavailable.
• Add a first-class, mobile-friendly, browser-only flow to mint a free-trial *.alpha.agent.agi.eth ENS subname via the FreeTrialSubdomainRegistrar while remaining technically honest (free registration, gas only, time-limited trial).
• Remove synthesized active-job truth so the UI no longer presents inferred job IDs as authoritative when event indexing is degraded.
• Keep the single-file, mainnet-first UI, preserve all v26 surfaces, and integrate the new flow into mission control, command palette, and mobile shell for discoverability.

Description

• ENS preview hardening: updated resolveEnsJobPagesContract() to prefer AGIJobManager.ensJobPages() on live connected mainnet, otherwise use the verified fallback 0x06188e...; updateEnsJobPagePreview() now reads snapshot-aware methods (jobLabelSnapshot, jobEnsLabel, jobEnsName, jobEnsURI, jobEnsNode) and never invents job-<id> labels; readiness text remains honest about public vs internal readiness.
• Free-trial registrar: added FreeTrialSubdomainRegistrar ABI, constants (FREE_TRIAL_SUBDOMAIN_REGISTRAR, FREE_TRIAL_PARENT_NAME, FREE_TRIAL_PARENT_NODE), and UI panel (alphaAgentMintSection) with public registrar state card, strict client-side label validation (8–63 chars, a-z0-9 only, no dots/hyphens/spaces), live availability via validateLabel + available, child node preview via namehash, registerSimple(parentNode,label,newOwner) review modal, and post-success handling that parses events, stores recent names, auto-fills agentSub, and calls verifySubdomain('agent', true).
• Admin & expert support: added a registrar admin posture card and parent-manager controls gated by NameWrapper.canModifyName(...), plus an advanced register(...) accordion for expert use (resolver, fuses, raw records).
• Synthetic-ID removal: replaced inferred active-ID fallbacks in getActiveJobIdsFromEvents() so degraded reads now return an explicit degraded state (no synthetic IDs presented) and surface clear warnings.
• UX & integration: wired the mint path into missionControl, command palette (Mint free alpha-agent ENS / Refresh registrar state / Open registrar controls), and mobile sheet (Mint free alpha-agent ENS shortcut); preserved and extended v26 mobile shell and kept all existing verify flows/UI surfaces intact.
• Small housekeeping: bumped visible version strings to v27, added NameWrapper supplemental reads needed for registrar admin checks, kept AGIJobManager, ENSJobPages, and FreeTrialSubdomainRegistrar as distinct systems, and preserved single-file architecture (ui/agijobmanager_genesis_job_mainnet_2026-03-05-v27.html).

Testing

• Static script syntax check: extracted inline scripts and ran node --check /tmp/v27.js, which returned OK.
• Basic automated validation: ran rg searches to confirm no forbidden legacy references (0xc19A84..., alpha.jobs.agi.eth) or raw alert/confirm/prompt calls; pattern checks returned clean.
• Functional smoke render: launched a headless browser view and captured a mobile screenshot of the new mint section to validate layout and mobile ergonomics (screenshot artifact generated).
• Local integration: exercised runtime wiring via page-level flows (connect wiring, registrar refresh, updateAlphaAgentMintPreview, and registerSimple review modal wiring) and validated that registerSimple is used as the default happy-path in the UI review modal (value = 0 ETH shown).

Remove the stray closing div in admin controls section

This extra </div> leaves the document with one more closing div than opening div, so the parser closes a parent wrapper early and later sections render outside the intended layout container. In practice this can break spacing/responsiveness for everything after the admin controls block and leaves the final container close unmatched.
