Merging dev to main userdash mvp complete.

Changes

Added routes for userdash / meal_log, meal_plan, workout_log, workout_plan
Added filter to userdash by item name
Created API endpoints for adding, deleting, updating and finding records that access the collections.js class
Changed deletion modal to execute request in component and return json response to callback.
Created modals for adding fooditems and workouts to logs

Views for workouts and fooditems
Collapsing tables to view nutritional information of fooditems e.g. carbs, fats, sugars, protein, calories
Centered register menu

Changed Nav (which will probably be scrapped in the future as far as I know) to be responsive
Made a hero component with welcome text
Included a button to sign up for membership
6 cards describing the gyms facilities for potential members (see user story 02 and use case 01 on docs)
Included a pricing table with 3 buttons for choosing your payment plan (all lead to the same sign-up page)

Login & Register now pages instead of components as single use unnecessary abstractions of route pages.
Login & Register no longer have <main class="h-screen"> as now taken care of by layout, this stops the pages from overflowing into the header on some devices.
