Tegy Billing Modal Corrections

Follow-up to issue #569. This report verifies the billing modal color, icon, close action, pricing-card removal, and iPhone-width mobile layout after the review notes on the previous video frame.

Corrections

Area	Before	Now
Color	Custom near-white billing modal and welcome splash.	Corrected: Tegy semantic dark surfaces, matching the workspace palette.
Plan icon	Diamond/gem glyph.	Corrected: network/plan glyph closer to Claude's free-plan iconography.
Close action	Top close plus an extra footer `Close` button.	Corrected: only the top-right icon close remains.
Pricing card	Extra right-side card with seats, price, and renewal date.	Corrected: removed from the free-plan settings modal; payment details stay in billing provider/management surfaces.
Mobile	No explicit iPhone parity check.	Corrected: iPhone 393x852 check with horizontal settings tabs and no overflow.
