Issue 96, 86, 85, 78

[Daraujo26]

[issue 96, 78] This code has the calendar pop up working and allows changes on the date selected inside create-journal-entry.

TODO:

1. The database needs to be updated to be able to store this selected date.
2. There may need to be minor UI adjustments on the calendar to match exactly whats on figma.

[issue 86, 85] I also went ahead and started reformatting the homepage to match whats on figma e.g. the profile and search button in the top right. I also fixed the add button on the bottom of the homepage. In the create page, I added the button in the bottom right as in figma so it shows a pop up for future actions to implement.

TODO:

1. Add icons inside the actions popover in the create journal entry
