Deployment monitoring db stability

[tyronechrisharris]

release: harden OSCAR 3.5.1 deployment, monitoring, and DB stability

• fix PostGIS datastore Hikari configuration to reduce idle connection hoarding
  by lowering pool sizing, setting minimumIdle=0, and shortening idle retention
• add profile-based JVM/Postgres sizing driven by .env for RPI4/8GB/16GB/32GB
• update Linux and Windows launch scripts to validate prerequisites, honor
  already-running OSCAR instances, and support clean FORCE_RESTART behavior
• update monitor scripts to support attach-vs-restart handling, bounded waits,
  and better startup diagnostics
• update launch-all scripts so container handling matches process-handling logic
  end to end
• add dependency checks for Java 21+, Docker, keytool, and PowerShell/CIM paths
• improve Windows startup reliability by removing WMIC dependence, fixing trust
  store discovery, and handling fresh-install password/bootstrap behavior
• update env.template with restart/attach and readiness settings
• ensure build/packaging outputs the correct 3.5.1 release artifacts and marks
  new shell scripts executable
• expand deployment docs for fresh unzip-and-run installs, sessionless launch,
  monitoring-first startup, MediaMTX proxy usage, and cleanup of older 3.5.0
  installs
• polish README, manual, launch/monitor guide, changelog, and release notes
• document remaining reconnect/thread issues as still under observation
