Fix BIRD inconsistencies

[ipspace]

• BIRD capitalization should be either 'BIRD' for product name or 'bird' for device name.
• BIRD CLI interface has been renamed from 'birdc' to 'birdcl'
• Removed a separate 'daemons' part of various platform support tables and added BIRD (or dnsmasq) to the main table.

Fixes #3505

[Copilot]

Pull request overview

This PR resolves BIRD-related inconsistencies by aligning CLI invocation (birdcl) with the shipped container image and standardizing documentation capitalization and support tables to treat BIRD/dnsmasq like other platforms (rather than listing them in separate “daemons” tables).

Changes:

• Updated BIRD daemon netlab_show_command to use birdcl instead of birdc.
• Standardized documentation capitalization to “BIRD” and integrated BIRD/dnsmasq into the primary platform support tables.
• Removed redundant “also supported on these daemons” sections where BIRD/dnsmasq are now listed in the main tables.
