Fix/camera bug fixes

[Archdoog]

Issue/Motivation

• Corrects a continuation leak case by moving the cancellation for a new task inside the closure.
• Consolidates camera zoom and pitch update to the most reliable method. We were seeing cases in ferrostar where the zoom with animation inside the set tracking with animation doesn't compete the zoom behavior some of the time. Using the direct setter seems way more reliable, even if it does look a tiny bit more jarring.

Tasklist

• Include tests (if applicable) and examples (new or edits)
• If there are any visual changes as a result, include before/after screenshots and/or videos
• Add #fixes with the issue number that this PR addresses
• Update any documentation for affected APIs
