Refactors user data queries

[xwilson03]

Description:

Replaces heavily duplicated user data queries with functions that return new standard user interface types.

Closes #96
Depends on #77

Reviewers:

• Required: @christianhelp
• Optional: @Lermatroid

Review Guide:

db/types.ts:

• Should interfaces other than Hacker include their relations?

  • Notable: Scan.user, Scan.event, potentially User.DiscordVerification

• Should redundant fields be removed from interfaces with relations?

  • e.g., either Hacker.teamID or Hacker.team.id would be removed.
  • Prevents interface compatibility with raw queries

• Clerk exports a User interface as well; is this an issue?

  • Research interface redeclaration behavior when importing from different modules
  • If problematic, could be avoided by prefixing all HackKit interfaces (User, Hacker, Event, Scan, Team)
    • hkUser, HKUser, or other ideas

db/functions/:

• Does the current spread of functions cover enough functionality, or are there expected behaviors missing?
  • See point 2 of above (redundant field removal)
• Should simple lookup functions be made for non- User or Hacker types? i.e., Scan, Event, and Team

Changelog:

• Adds db/types.ts to house database-specific types

  • Converts existing db types to interfaces for cleaner IntelliSense (User, Event, Scan)
  • Renames UserWithAllData to Hacker and makes team property optional
  • Replaces InferModel calls with new interfaces across codebase

• Adds db/functions folder to house common queries and reduce code duplication

  • User + Hacker: get(*), get(*)ByTag, getAll(*)s
  • Hacker: functions include withTeam flag for optional data inclusion

• Replaces raw queries with functions where possible

  • Refactors transactions in scanner and check-in

For future reference and reviewer sanity, it might be nice to point this PR to the sister PR #77 and then point it back to dev afterwards just so we don't have to go through a lot of the same files bc 58 files is a lot.

Issues have been resolved.
