Onboarding Flow Implementation

[varunbln]

This PR adds the core functionalities of the onboarding flow. Here is a checklist of the features added that were mentioned in issue #2

• Geosearch input ✅
• Vertex control immediately active ✅
• Sidebar updates with acres submitted ✅
• Ask for name and email ✅
• Email sent to submitter ✅
• Email sent to admin when someone submits ✅
• Magic link auth ✅
• Thank you for submitting page ✅
• Dashboard showing current step the submission is in ✅
• Step 1 collects various details like phone number, etc ✅
• All this updates in db ✅

Additional features not in the scope I implemented:

• Switch to Google Maps API for hybrid(terrain + street view)
• Converted repo to a typescript project
• Misc bug fixes

I've attached a demo video where all these features are visible at the end of the PR.

The purpose of this submission is to lock in one of the first 4 applicant spots since its based on who submits a reasonably finished PR first. I think it implements all the features in the scope, let me know if I'm missing anything.

If I get approval that this is reasonably finished, and there's no core functionality from the scope I'm missing, I'll get started on some bonus features I have planned as well as prettifying the email templates and app in general.
