Add support for importing routing rules via deep link

---

Description:

Right now, V2RayNG supports importing connection settings through deep links, but it doesn’t allow importing routing rules. Adding this feature would make the app much more user-friendly, especially for advanced configurations.

---

Why this is useful:

1. Users can quickly load routing rules from a web app or other sources with one click.
2. It saves time compared to manually configuring or importing files;

---

How it could work:

Add support for a deep link like this:

v2rayng://routing-rules?rules=<encoded_rules>

• <encoded_rules>: Base64-encoded JSON of routing rules.

---

Example Rules:

[
    {
        "domain": [
            "geosite:youtube",
            "geosite:facebook",
            "domain:googlevideo.com"
        ],
        "enabled": true,
        "locked": false,
        "outboundTag": "proxy",
        "remarks": "Blocked services"
    },
    {
        "domain": [
            "domain:speedtest.net"
        ],
        "enabled": true,
        "locked": false,
        "outboundTag": "proxy",
        "remarks": "Speedtest"
    },
    {
        "domain": [
            "regexp:.*$"
        ],
        "enabled": true,
        "locked": false,
        "outboundTag": "direct",
        "remarks": "Direct all"
    }
]

Encoded in Base64:

Notes:

This feature already exists in V2RayTun (Android) and Streisand (iOS). It would be great to see it in V2RayNG too!
