Update based on QA document

[zoek1]

Description

• [X] Buy and Redeem modal UI should be updated in line with Figma
• [x] Once a pToken has been created, the Create bar should change to an Edit bar with the text 'Modify your Personal Token' - NEEDS EDIT BUTTON TO REPLACE CREATE BUTTON
• [x] When using Edit, the user should not be able to change the Token Name or Token symbol.
• [x] Add Personal Token icon to blank Open section followed by a button "Browse Tokens" with a link to User Explorer
• [x] Redeem Modal needs to reference how many tokens the user is holding and ensure no more than that amount can be requested.
• [x] Filter needs to match users who have created a pToken. Right now it is not mapped to the database properly. STILL NOT FILTERING PROPERLY
• [X] update modals for buy tokens aligned to figma design
