ISSUE-151: Memory issues with Buckets + Refactoring

[Ammar-T]

Details

• After making the bucket and list views synched with the board in terms of likes, comments, text changes, there was a bug introduced which led to a lot of listeners being created, which affected everything on the app. The canvas was laggy due to the countless listeners and read/writes happening.
• This PR removes our original side panel which kept the listeners active even after the panel was closed. I've tried using the ngOnDestroy method however it wouldn't work for the panels. So, instead of having side panels, I moved our bucket and list view into modals which resolved the issue and kept our original functionality.

Smaller Changes:

• Added small black border to all posts (both canvas and modal posts)
• Centered "Forgot Password" text on login page
• Wait for project to load until name and other info is printed (was showing errors in console)
• Renamed post component classes to differ between fabric and HTML posts
• Reworked HTML posts to use flexbox for better experience with list/buckets modal

Closes #151
