Feat: REST ticket type management and event creation

[tarynblakemiller]

This PR has admittedly expanded as I arrived at event creation!!

I should note that I pulled in Jack's DB models branch in order to finish this.

Description

• RESTful ticket type management
• Event creation and management
• Image uploading

Type of Change

• Bug fix
• New feature
• Breaking change
• Documentation update

Changes Implemented

CRUD operations for ticket types

• src/app/tickets.rs

GET /tickets - List all ticket types
GET /tickets/new - Creation form
POST /tickets/new - Create ticket
GET /tickets/{id} - View ticket (read-only)
GET /tickets/{id}/edit - Edit form
POST /tickets/{id}/edit - Update ticket
POST /tickets/{id}/delete - Delete ticket

Events can now be created with a ticket type and flyer image

• src/app/events.rs

GET /events - List events with cover image thumbnails
GET /events/new - Creation form with ticket selection
POST /events/new - Create event with tickets and image
GET /events/{id} - View event (read-only with ticket details)
GET /events/{id}/edit - Edit form
POST /events/{id}/edit - Update event
POST /events/{id}/delete - Delete event

##Image Processing

**this was just a placeholder please feel free to critique and change!
I added an image processing module to the templates and a temporary storage path for images.

This added base64 and uuid dependencies.

Storage path: frontend/static/uploads/images/events/
Web path: /static/uploads/images/events/

• the DB stores the web path for template rendering

Testing

• make a directory for image uploads at frontend/static/uploads/images/events

Ticket Types

• Visit /tickets to create a new ticket type
• click on ticket name to view read-only details
• Edit, modify, and save --> should redirect to view

Event Creation

• create a ticket type first because as of now they're required for events
• Visit /events/new to create an event with a cover image
• Test with different formats - restricted to JPEG, PNG, GIF, WebP at the moment
• Click on an event from the list -- should take you to the view page with details
• Edit, modify and save the changes
• Test event deletion
