Resources tab: Add statsig logging to triggered tours

[molly-moen]

This adds statsig logging to tours triggered via the resource tab. I did a little refactoring to share metric names between the auto-triggered tours and the resource tab-triggered tours.
I also found a styling bug in the tour play button, it wasn't using MUI styles and was not theming correctly. I switched it to use MUI styles, and they now match the mocks.

Pull request overview

Adds richer analytics logging for product tours started from the Resources tab, and refactors tour configuration so analytics “flowName” values are sourced consistently from a shared configuration object.

Changes:

• Introduces TriggerSource and includes it in intro-flow analytics events for both auto-triggered tours and Resources-tab-triggered tours.
• Refactors product tour configs to include a shared metricName, removing duplicated flow-name constants.
• Fixes the Resources tab “play tour” button styling by switching to MUI IconButton styling props.
