Integrate FreeTrialSubdomainRegistrar and add alpha-agent ENS mint UI (plus mobile IDs and misc fixes)

[MontrealAI]

Motivation

• Provide an in-browser, guided flow to mint free-trial *.alpha.agent.agi.eth ENS subnames via the on-chain FreeTrialSubdomainRegistrar and surface registrar state to users.
• Make registrar management and preview flows robust (validation, availability, parent status, recent names) and safe by adding a transaction review modal before minting.
• Unify related UX identifiers for the mobile dock/sheet and adjust small protocol/version labels to match the UI version.

Description

• Added FreeTrialSubdomainRegistrar ABI (including NameRegistered event) and wired up contracts with new runtime state: freeTrialRegistrar, registrarWrapperContract, and APP_STATE.registrar fields.
• Introduced a minting UI: mintGrid, mintPreview, inline validation (validateAlphaLabelLocal), preview fields (mintAlphaFullName, mintAlphaEnsUri, mintAlphaNode, mintAlphaAvailability, mintAlphaExpectedExpiry), a transaction review modal (alphaMintReviewModal), and a mintAlphaAgentName flow that calls registerSimple.
• Added registrar admin controls (registrarAdminControls) for parent managers, recent-name persistence under the key agijobmanager_v27_recent_alpha_names → agijobmanager_v26_recent_alpha_names (now RECENT_ALPHA_AGENT_KEY), and functions to refresh and render registrar state (refreshFreeTrialRegistrarState, renderRegistrarAdminControls, updateAlphaMintPreview).
• Small protocol/UI updates: ensure ENSJobPages getter fallback wording, adjust token/metadata createdVia and packet version to v26, add command palette entry to copy previewed minted name, and improve status copy/paste helpers.
• Renamed mobile enhancement identifiers and handlers from v27* to v26* across styles and the mobile script to keep naming consistent with the UI version.

Testing

• No automated tests were added or executed as part of this change.

Escape recent names before writing them into innerHTML

The recent-name renderer now injects name directly into innerHTML for both element text and the data-alpha-recent attribute, which creates a stored XSS vector if localStorage[RECENT_ALPHA_AGENT_KEY] is ever poisoned (for example by another same-origin script or manual/local tooling edits). This regression is introduced in this commit because the previous path escaped these values before interpolation; keeping this unescaped means a crafted value can break out of the attribute/text context and execute script when the panel renders.
