fix: remove sticky positioning from page headers in pages on scroll

[eeshm]

What does this PR do?

Headers and subheaders were fixed to the top when scrolling on some pages like workflows, routing forms, and org members pages.

Only some pages showed this behaviour because other pages (event types, bookings) use ShellMainAppDir which never had sticky position.

• Fixes Remove fixed headers and subheaders on scroll #27229
• Fixes CAL-7124

Visual Demo (For contributors especially)

• before :

• after

cursorful-video-1769430334656.mp4

Mandatory Tasks (DO NOT REMOVE)

• I have self-reviewed the code (A decent size PR without self-review might be rejected).
• I have updated the developer docs in /docs if this PR makes changes that would require a documentation change. N/A
• I confirm automated tests are in place that prove my fix is effective or that my feature works.

How should this be tested?

• no breaking changes
• Go to workflows page, the header scrolls with content.
• all pages using ShellMain fixed

@eeshm i have pushed one commit, this works as expected on workflows pages and not creating regression on other pages, could you please check if what i pushed is the optimal solution and if yes could you apply the same on other pages as well? if this is not optimal, please feel free to change the implementation.

please check all the pages after your fix, and attach all the videos

hi, thanks for catching it and sorry my approach was too broad. Your approach mostly look fine, i'll verify it locally and apply changes on other pages.

hi @dhairyashiil, checked locally and your fix was optimal and is not creating regression on other pages.

additional changes applied to:

• apps/routing-forms/forms/[[...pages]]/Forms.tsx - Routing Forms page
• settings/organizations/(org-user-only)/[id]/members/layout.tsx - Org Members view
• settings/platform/members/layout.tsx - Platform Members view

videos:

• cursorful-video-1769445896650.mp4
• cursorful-video-1769450246704.mp4

• /settings/platform/members - can't verify (subscription needed) ), but follows the same pattern
