Promote 0.1.10 to the current stable Walter On-Prem release
Add mix walter.release.prepare so Walter release prep updates the app version, on-prem manifest, release notes, and generated site manifest in one step
Remove the managed system reporting selector from self-hosted admin settings so on-prem installs no longer surface AWS Marketplace reporting controls
Operator notes
bin/walter-onprem upgrade now resolves to 0.1.10 for existing 0.1.x installs
No new migration step or deployment configuration is required for this release
Maintainer release prep is now scripted, but operator install and upgrade behavior is otherwise unchanged
