[wineee]

1. Add pam_deepin_keyring to auth and session stacks in ddm.pam
2. Add pam_deepin_keyring to auth and session stacks in debian.ddm.pam
3. Add pam_deepin_keyring to ddm-autologin.pam for passwordless login
4. Recommend deepin-keyring-whitebox package in debian/control

Log: No user-facing changes

Influence:

1. Verify normal password login unlocks the keyring without error
2. Verify autologin and nopasswdlogin unlock the keyring seamlessly
3. Verify login still works when deepin-keyring-whitebox is not installed

feat: 为 PAM 服务增加 pam_deepin_keyring 支持

1. 在 ddm.pam 的 auth 和 session 栈中加入 pam_deepin_keyring
2. 在 debian.ddm.pam 的 auth 和 session 栈中加入 pam_deepin_keyring
3. 在 ddm-autologin.pam 中加入 pam_deepin_keyring 以支持免密登录
4. 在 debian/control 中推荐安装 deepin-keyring-whitebox 包

Log: 无用户可见变化

Influence:

1. 验证正常密码登录后密钥环能被解锁且无报错
2. 验证自动登录和免密登录时密钥环能正常解锁
3. 验证未安装 deepin-keyring-whitebox 时登录仍能正常进行

PMS: TASK-390751

Reviewer's guide (collapsed on small PRs)

Reviewer's Guide

The PAM service definitions now invoke pam_deepin_keyring across normal, Debian-specific, autologin, and passwordless login paths, while packaging recommends deepin-keyring-whitebox so keyring integration is available without preventing login when the package is absent.
