Upload rework

See merge request !1

finished botched middle-of-upload cancellation(can't directly abort uploader at the moment, settled for location.reload()); added working middle-of-upload submission(request gets sent as soon as the upload finishes)

Added storage space upgrading; added code manager (runnable with npm run codes), added more stat cards for dashboard;

Fixed remaining space calculation bug; fixed confirmed videos getting removed from the database on launch; fixed video cancellation bug

updated video confirmation route to work with changed domain; updated video upload finalization confirmation messaging

Adjusted upload modal; reworked fideo finalization flow; fixed video confirmation bug; fixed video fetching

added separate admin panel that display various statistics + all uploaded videos. Added route to retreive said stats.

implemented video removal route, the space that the video took up gets re-added to the user's remaining space;

implemented video view counting; improved error displays with messages; implemented uploaded video space tracking, now video size is properly deducted from user's remaining space.

reformatted dashboard into a table structure for better accessibility and scaling; added backbone for video stat system.

Reworked dashboard video list fetching; various other fixes. [currently only the first video fetch returns the actual videos, subsequent ones 404. Will be fixed next commit]

finished id-based video fetcher & player; changed id schemes because underscores and dashes did not play along with nuxt params

finished video validation route. Added loading animations while validating requested video(acts as a fallback for video validation at the moment because those operations get completed before rendering the page itself)

added layout for video page; added video verification route [WIP] that gets called when a video is requested;
