feat(cli): redesign route output as multi-line indented format

[fanyang89]

Summary

• Redesign easytier-cli route output to use tabled table format instead of multi-line text
• Add --wide/-w global option to show extended route information
• Implement intelligent table wrapping to adapt to terminal width
• Remove Version column for cleaner display

Default output (6 columns):

| Hostname | IPv4          | Via     | Hops | Latency | Proxy          |
|----------|---------------|---------|------|---------|----------------|
| node-1   | 10.10.10.1/24 | (local) | -    | -       | 192.168.1.0/24 |
| peer-a   | 10.10.10.2/24 | DIRECT  | 1    | 12ms    |                |
| peer-c   | 10.10.10.3/24 | peer-b  | 2    | 45ms    |                |

Wide output (-w flag, 7 columns):

| Hostname | IPv4          | Via     | Hops | Latency | Lat-First                      | Proxy          |
|----------|---------------|---------|------|---------|--------------------------------|----------------|
| node-1   | 10.10.10.1/24 | (local) | -    | -       | -                              | 192.168.1.0/24 |
| peer-a   | 10.10.10.2/24 | DIRECT  | 1    | 12ms    | -                              |                |
| peer-c   | 10.10.10.3/24 | peer-b  | 2    | 45ms    | via: peer-d                    |                |
|          |               |         |      |         | hops: 3                        |                |
|          |               |         |      |         | latency: 30ms                  |                |

Changes

• RouteTableItem and RouteTableItemWide structures using tabled::Tabled
• print_output() function enhanced with wrapping support:
  • table.modify(Rows::new(1..), Width::wrap(terminal_width)) for data rows only
  • Headers remain unwrapped for clarity
• Version column removed from wide mode to improve display
• JSON output format includes all fields (including version)
• Verbose mode (-v) behavior unchanged

Breaking Changes

• --no-trunc flag renamed to --wide/-w
• Default output format changed from multi-line text to table

Pull request overview

This pull request redesigns the route command output from a wide 13-column table to a more readable multi-line indented format inspired by the ip route command style. The change makes the output more terminal-friendly by eliminating horizontal scrolling and presenting each route entry across multiple lines with clear key-value labeling.

Changes:

• Replaced RouteTableItem (with tabled::Tabled trait) with RouteItem (only serde::Serialize) to support custom text formatting
• Implemented multi-line output format with 2-4 lines per route entry, showing identifier, hostname/version, routing info, and optional latency-first path
• Modified next_hop logic to prefer hostname over IP address for better readability
