[Feature]: Support LDAP Authentication for Dashboard Login

[davedwwang]

Why are the changes needed?

The current Dashboard login uses an admin-user with a plaintext password, which is highly insecure. To enhance security, centralize user management, and align with industry standard practices, we need to switch to LDAP authentication.

Close #4008.

Brief change log

• Introduced three new login-related configurations in AmoroManagementConf.
• Added LdapPasswdAuthenticationProvider to support LDAP integration (implements PasswdAuthenticationProvider).
• Updated LoginController to use PasswdAuthenticationProvider for user login validation.

How was this patch tested?

• Add some test cases that check the changes thoroughly including negative and positive cases if possible

• Run test locally before making a pull request

Documentation

• Does this pull request introduce a new feature? (yes / no) yes
• If yes, how is the feature documented? (not applicable / docs / JavaDocs / not documented) not documented
