refactor(constants, types): moved to proper files

[Examplio]

Constants, some types have been moved to the corresponding file. Also, a new constant for the API/servers/... path

Sorry, but I’m closing this PR.

It looks like this was generated by AI.
There are many unnecessary changes mixed in with the actual goal.

Example:

• Moving UI data into constants (it would have API URLs, UI Assets and Social Links)
• Renaming and moving around imports (why?)
• Adding .ts extensions to imports (?????)

Not AI lol. const must be in costants.ts. Otherwise, I don't know.
