fix: prevent auto-switch to unavailable audio ports

[MyLeeJiEun]

修复禁用有线耳机和USB扬声器端口时输出设置错误切换为HDMI的问题

问题描述

禁用有线耳机和USB扬声器端口后，输出设置错误切换为HDMI，且音频仍从有线耳机输出。

修改内容

1. audio1/priority_manager.go：refreshPorts 移除对 AvailableTypeNo 端口的过滤，仅按 !pc.Enabled 跳过，临时不可用但已启用的端口保留在优先级队列中
2. audio1/audio_events.go：checkAutoSwitchOutputPort / checkAutoSwitchInputPort 新增端口可用性检查，Available == AvailableTypeNo 时跳过，避免自动切换到不可用端口

Summary by Sourcery

Prevent automatic audio routing from selecting unavailable ports while preserving enabled ports across transient availability changes.

Bug Fixes:

• Prevent automatic audio input and output switching to ports that are currently unavailable.
• Preserve enabled but temporarily unavailable ports in the priority queue to avoid incorrect fallback switching during profile transitions.

Reviewer's Guide

The fix separates priority-list membership from current port availability: enabled ports remain prioritized through transient profile states, while auto-switch logic checks availability at selection time and skips unavailable input or output candidates.

Preserve enabled but temporarily unavailable ports in the priority queue instead of removing them during port refresh.	Filter refreshed ports only by the user-enabled setting. Retain unavailable ports so transient profile changes do not delete their priority entries.	audio1/priority_manager.go
Prevent automatic input and output switching from selecting currently unavailable ports.	Retrieve output port metadata and skip candidates marked unavailable. Skip unavailable input candidates while evaluating the priority list. Continue evaluating lower-priority candidates when a port is unavailable.	audio1/audio_events.go

Hi @MyLeeJiEun. Thanks for your PR.

I'm waiting for a linuxdeepin member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
