docs: Clarify baremetal network requirements and kubectl capabilities

[rahulbabu95]

Description of changes:

• Qualify L2 network as network/PXE boot only, not required for ISO boot
• Clarify DHCP only needed for network/PXE boot mode
• Add TinkerbellIP vs Control Plane Endpoint explanation
• Clarify kubectl works for management and workload cluster operations
• Add hardware CSV operational guidance (when to use CSV vs kubectl)
• Add cross-references between related documentation

These changes address common customer confusion about network requirements for different boot modes and the scope of kubectl usage for cluster lifecycle management.
