feat: implement persistent remember-me authentication and update Docker Actuator healthchecks

[podlLev]

Overview

This PR adds database-backed "Remember-Me" persistent token authentication to preserve user session states across browser restarts. Additionally, it refactors the Docker deployment configuration to isolate operational monitoring by routing container health checks through a dedicated management port.

Key Changes

• Database & Security Architecture (Remember-Me):

  • Schema Extension: Added the standard persistent_logins database table migration script to securely store series tokens, usernames, and last-used timestamps.
  • Configuration Properties: Configured application properties specifying the remember-me secret key and custom token validity durations.
  • Spring Security Wiring: Wired PersistentTokenBasedRememberMeServices (or JDBC token repository) into the security filter chain to enable persistent token authentication upon sign-in.

• User Interface Enhancements:

  • Sign-In View: Added a "Remember Me" checkbox component to the login form interface to capture user session preferences during authentication.

• Container Infrastructure & Monitoring:

  • Actuator Isolation: Exposed a dedicated management port in Docker configurations and updated container HEALTHCHECK directives to probe Spring Boot Actuator endpoints on this dedicated port instead of public traffic routes.
