Upgrade of shipped sample projects

[nirvn]

This PR upgrades the sample projects QField ships with. Major changes include:

• Merging simple and advanced bees farming sample project into a single project
• Significant symbology upgrades to the bees farming project
• Significant rework of the layouts shipped with the bees farming project
• A brand new wastewater management sample project (using a subset of QGEP sample data), served in both light and dark themes

Note that this comes at the cost of a slightly larger APK (due to the need to ship some additional datasets), but very much worth it as this revamp does a much better job at showing off QField's capabilities.
