added series of login pages

[rohansarikonda]

added login pages (login, forgot password, create account, verify email, change password)
some ui elements are not on-theme (still use material themes), will work on that as well
i think most functionality is there; most pages check for existence of required fields (email, password, verification code, etc)

Now that Arya has shared the logo, can you update the login page to include the logo?

• Enforces input types on username, password
• Routes to create account page
• Routes to home page

[aryavenkatesan]

• Can you make the login button route to the bottom_bar component
• Add the logo to the login page

hey, both of those should be done now. let me know if anything remains to be done!
