[PB-557] fix/file size as number

[jzunigax2]

Similar to #321, file size's type is changed from BigInt to Number. This would be a breaking change for the mac desktop client, but convertSizeMiddleware is applied to problematic routes as reported by @PixoDev in order to convert the numeric size into string. These routes are:

• PUT /files/:fileUUID
• GET /files/:fileUUID/meta
• GET /folders/:folderId/files
• GET /files?updatedAt=ISODate

@jzunigax2 There are better ways to achieve this without mutating functions, which could have unforeseen effects in future NestJS versions. Let's implement this in a more standard NestJS way.

How about using NestJS Interceptors? They allow you to execute code before and after the handler (where you can implement your current solution). Additionally, interceptors can be bound to controllers.

With the execution context you should have access to the headers too
