Beautify the NoteCard and PasswordCard

[RohanKaran]

Is your feature request related to a problem? Please describe.

• Currently both NoteCard and PasswordCard has very basic UI. Try to improve it.

Describe the solution you'd like

• Improve the overall structure, fonts, ratio, size especially the buttons requires improvement. Also try to improve the Delete pop up modal
• Keep the basic workflow same(e.g. password or the notes content should not be visible by default)
• Do not install additional UI library. Use React-Bootstrap only. Write custom CSS for modification.
• Use Font Awesome icons only.
