feat: Add proxy list, proxy reject, and proxy remove --all

[MkDev11]

Description

Closes #742

Adds the missing proxy commands and flag from issue #742.

New commands:

• btcli proxy list — Lists proxies for an account by querying chain storage Proxy.Proxies. Optional --address (defaults to selected wallet). Supports --json-output.
• btcli proxy reject — Rejects a previously announced proxy call via Proxy.reject_announcement. Optional --delegate (defaults to wallet coldkey). Resolves --call-hash from the ProxyAnnouncements table when available and marks the announcement as executed on success (same flow as btcli proxy execute).

Modified command:

• btcli proxy remove — Added --all flag to remove every proxy for the account in one call (Proxy.remove_proxies). --all and --delegate are mutually exclusive; one is required.

Changes

• bittensor_cli/src/commands/proxy.py: Added _parse_proxy_storage, list_proxies, reject_announcement, remove_all_proxies; handles nested substrate response formats using decode_account_id.
• bittensor_cli/cli.py: Registered proxy list and proxy reject; extended proxy_remove with --all flag (mutually exclusive with --delegate); proxy_reject integrates with ProxyAnnouncements (resolve call_hash, mark_as_executed on success).
• tests/unit_tests/test_cli.py: 7 tests for _parse_proxy_storage (None, non-sequence, dict format, dict proxy_type, tuple unwrap, empty list, malformed entries, delegatee key); tests for list_proxies (success, JSON, empty, error); tests for remove_all_proxies (success, prompt declined, unlock failure); tests for reject_announcement (success, JSON, prompt declined, failure); CLI handler tests for proxy_remove (mutual exclusivity, require delegate or all, --all vs --delegate), proxy_list (with/without address), proxy_reject.
• tests/e2e_tests/test_proxy.py: E2E test test_proxy_list (add proxy, list, verify delegate in output, cleanup).

Testing

• Unit: pytest tests/unit_tests/test_cli.py — 55 passed.
• Lint: ruff check bittensor_cli/src/commands/proxy.py bittensor_cli/cli.py tests/unit_tests/test_cli.py tests/e2e_tests/test_proxy.py — all checks passed.
• E2E (with local chain): pytest tests/e2e_tests/test_proxy.py -v -k "test_proxy_list".

Checklist

• Code formatted with ruff; tests pass.
• Branch off staging (or target staging when opening the PR).
• New feature includes tests (unit + e2e).
• PR description explains what changes do and which issue is resolved.

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

I think overall this is fine, but I need some time to do some deeper review/testing, as it's a large PR. I'll make it a point to do this next week.

CI test errors are gone. please review the changes when you are available. thanks.

CI error is a flaky issue not related to my PR.

Hi, not sure it makes sense to add this right now. Code seems fine. Just still developing the architecture for btcli 10.0

[MkDev11]

Thanks for the reply. Totally get that 10.0 is still taking shape.
Just wanted to point out — right now on staging there's no way to list proxies or reject announced calls. So users can grant proxies but can't check what's there, and if a delegate announces something sketchy, there's no btcli command to cancel it. Both are just simple chain calls, no new patterns or anything — they'd move to 10.0 the same way the other proxy commands do.
