admin web functionality port

[mnpqraven]

from previous react sites

• tag table
• tag action col
• tag view/edit
• blog meta table
• figure out how should we deal with md files and images (leaning into local FHS)
• blog meta edit page(later md content needs to be editable as well)
• auth, only accessible with credentials/github oauth
• error handling is a mess with all the error struct between different workspaces
