feat: Add hyperparams: sudo_set_sn_owner_hotkey, sudo_set_subnet_owner_hotkey, sudo_set_recycle_or_burn

[MkDev11]

Summary

Adds three hyperparameters as first-class CLI params so they can be set via btcli sudo set --param <name> --value <value>. They were previously unreachable because the arbitrary path only supports bool/u16/u64 and a single pallet.

Closes #826

Type of change

• New feature (non-breaking)
• Bug fix (hyperparams were invalid when set via arbitrary path)

What's changed

Param	Description
sudo_set_sn_owner_hotkey	Set subnet owner hotkey (root sudo only); value = SS58 hotkey
sudo_set_subnet_owner_hotkey	Alias of above (same extrinsic)
sudo_set_recycle_or_burn	Set recycle vs burn for subnet TAO (root sudo only); value = bool

• bittensor_cli/src/__init__.py: Added all three to HYPERPARAMS (alias maps to same extrinsic) and HYPERPARAMS_METADATA (descriptions, side_effects, owner_settable=False, docs_link).
• tests/unit_tests/test_hyperparams.py: New tests for presence in HYPERPARAMS, alias→same extrinsic, metadata, and owner_settable False.

No changes to sudo.py; existing first-class path already handles single extra arg (SS58 or bool).

@thewhaleking could you please review the PR and let me know your feedback? thanks.

The E2E tests are failing due to a CI infrastructure issue: the subtensor-localnet Docker artifact is corrupt (only 7.5KB), causing docker load to fail.
