FOUR-32573: Fix inbox list scrolling

[eiresendez]

Issue & Reproduction Steps

On /inbox, a task list containing enough items to exceed the available viewport height is clipped at 100% browser zoom. Users cannot reach the end of the list or its pagination controls without reducing the browser zoom.

To reproduce:

1. Open /inbox with more than 15 available tasks.
2. Keep the browser zoom at 100%.
3. Use a 1280×720 viewport or another viewport where the task list exceeds the available height.
4. Attempt to scroll to the pagination controls.

Solution

• Allow the Inbox content container to scroll when its content exceeds the available viewport height.
• Preserve the existing scrolling behavior for Process and Dashboard views.
• Keep the change scoped to ParticipantHomeScreen.vue.

How to Test

1. Open /inbox with more than 15 tasks at 100% browser zoom.
2. Confirm the complete task list and pagination controls are accessible through vertical scrolling.
3. Repeat the verification on the Inbox, Priority, and Drafts tabs.
4. Confirm Process and Dashboard views retain their existing scrolling behavior.

Validation performed:

• git diff --check passed.
• A targeted ESLint comparison against develop confirmed that the change introduces no new findings.
• Local browser validation was blocked by an unrelated Laravel bootstrap error: Target class [view] does not exist.
