fix: remove <> from allowed password characters and display allowed special chars

## Changes
- Remove < and > from password regex pattern in joi.js (these chars are
  stripped by DOMPurify sanitization which caused confusing validation errors)
- Update locale strings to display the list of allowed special characters
  in password tooltip, error messages, and PasswordPanel requirements

## Benefits
- Users now see exactly which special characters are allowed when setting passwords
- Eliminates confusing "password cannot be empty" errors when using < or >
- Regex now accurately reflects the characters that actually work

Fixes #3010
