Fix aspire config list --all showing no features when no config exists

[Copilot]

aspire config list --all with a fresh install (no config set) would hit an early-return path and only print "No configuration values found." — never displaying available feature flags. Similarly, aspire config list gave no hint to try --all.

Changes

• ConfigCommand.cs — ListCommand.ExecuteAsync: Replace the unconditional early-return on empty config with flag-aware branching:
  • config list (no --all, no config): show "No configuration values found." + hint to run --all, then return
  • config list --all (no config): show "No configuration values found." then fall through to display all feature flags with defaults/descriptions
  • Existing config present: behavior unchanged — render config tables then feature section
• ConfigCommandTests.cs: Two new tests covering the no-config cases for both with and without --all

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Pull request overview

Fixes aspire config list --all so that it still displays the available feature flags (with defaults/descriptions) even on a fresh install where no local/global config files exist, and improves the config list no-config UX by adding a hint to use --all.

Changes:

• Adjust config list control flow to avoid an unconditional early return when both local/global config are empty, while still keeping the “no config” message.
• Add a --all hint in the no-config + no---all case, and allow --all to fall through to the feature listing.
• Add unit tests covering both no-config scenarios (config list and config list --all).
