Add configurable password validation rules to user profiles

[Copilot]

Implements configurable password policies per user profile (简档), allowing administrators to enforce password complexity requirements like minimum length, character types (uppercase, lowercase, numbers, special characters), and maximum length.

Changes

Schema & Database

• Added 6 password policy fields to permission_set object: password_min_length, password_max_length, password_require_uppercase, password_require_lowercase, password_require_number, password_require_special_character
• Updated profile schema with corresponding field definitions
• Added zh-CN and en translations

Server-Side Validation

• Created UserProfilePolicy interface for type safety
• Implemented validatePasswordPolicy() method enforcing profile-specific rules in changePassword() and resetPassword() flows
• Extended getUserProfile() to fetch password policies from user's profile with NaN protection on numeric conversions
• Extracted SPECIAL_CHAR_PATTERN and DEFAULT_PASSWORD_POLICY constants to shared types

Client-Side & API

• Enhanced validatePassword() function to support structured policy fields while maintaining backward compatibility with regex-based policies
• Modified /api/accounts/settings endpoint to merge user-specific password policies when authenticated

Example Configuration

Profile with strict password requirements:

password_min_length: 12
password_max_length: 128
password_require_uppercase: true
password_require_lowercase: true
password_require_number: true
password_require_special_character: true

Validation errors returned to users:

密码长度不能少于 12 个字符
密码必须包含至少一个大写字母(A-Z)
密码必须包含至少一个特殊字符(如 !@#$%^&* 等)

Default values (min: 8, max: 128, all requirements: false) ensure existing profiles work without changes.
