Fix: Consistency in titles of different dapp pages

[marshall2112]

We need to replace all the page headers using the 1) Same Font; 2) Same font size as Claim from Vaults 3) Centered on the page

• Trade (need more white space buffer from the top of the page; use Claim from Vaults as Reference)
• Treasury (I'm not sure where to put it probably above the TRV/RAMOS/TLC... Subheaders)
• Temple Line of Credit
• Claim from Vaults / Unstake OG Temple << this is fine leave as-is

Background:
The Font, Font size, and modal position of the TRADE header should match the style of the other pages for cohesion.
Right now it's kind of random font / font sizes. I would pick one and go with that Font Face and size and horizontal alignment
OR alternatively just wait for the Spice Bazaar PR merge before harmonizing the headers and font sizes
