Add FreeTrialSubdomainRegistrar alpha-agent mint UI and registrar integration; ABI & mobile script refactor

[MontrealAI]

Motivation

• Provide an in-browser flow to mint free-trial *.alpha.agent.agi.eth ENS subnames via the on-chain FreeTrialSubdomainRegistrar and make the registrar state and availability checks first-class in the UI.
• Replace fragile expert-only register paths with a safer preview/review + registerSimple flow and persist recent names locally for convenience.
• Align ABIs and auxiliary hooks to match on-chain contract signatures and improve ENSJobPages preview reliability.
• Standardize mobile dock/sheet identifiers and downgrade the UI version string where appropriate to match packaging.

Description

• Added a new minting panel and UI controls for alpha-agent free-trial names: mintGrid, mintPreview, mintAlphaLabel, mintAlphaRecipient, mintAlphaAgentBtn, mintAlphaStatus, recentAlphaAgentNames, and an alphaMintReviewModal for transaction review.
• Integrated FreeTrialSubdomainRegistrar contract: added FreeTrialSubdomainRegistrarABI (including NameRegistered event), new constants (FREE_TRIAL_REGISTRAR, ALPHA_AGENT_PARENT, ALPHA_AGENT_PARENT_NODE), registrar wrapper handling, parent status reads, label validation, availability checks (available) and trial expiry display.
• Reworked client-side alpha-label handling: introduced normalizeAlphaLabel, validateAlphaLabelLocal, improved timestamp formatting via formatTimestamp, updated recent-name localStorage key to agijobmanager_v27_recent_alpha_names, and functions to load/save/render recent names.
• Replaced the previous expert/advanced register UI with a simpler, safer flow: preview → open review modal → registerSimple(parentNode,label,recipient) and added mintAlphaAgentName to run tracked txs and handle NameRegistered event outcomes.
• ABI and ENS job preview updates: adjusted MIN_LABEL_LENGTH/MAX_LABEL_LENGTH ABI types, added ENSJobPages getters (jobEnsLabel, jobEnsName, jobEnsURI, jobEnsNode) and improved ENS preview messaging.
• Miscellaneous UX, safety and housekeeping: tightened validation messages, updated various status messaging, changed internal build/version strings from v27 → v26 in a few places, and renamed mobile enhancement IDs/classes and script content from v27 → v26 (dock/sheet element and handler renames) to keep mobile shell consistent.

Testing

• No automated tests were run as part of this changeset; changes are primarily UI/JS front-end additions and ABI updates and should be validated via manual QA in a local/dev environment before production deployment.

Restore boolean output for validateLabel

FreeTrialSubdomainRegistrarABI now declares validateLabel with outputs: [], but the deployed registrar at FREE_TRIAL_REGISTRAR returns a boolean, so Web3 decodes .call() to an empty object instead of true/false; in updateAlphaMintPreview, that object path is treated as valid (isContractValid = true), which suppresses registrar-side invalid-label feedback and can let users attempt registerSimple on labels the contract would reject.
