When the orchestrator imports `block/core/internal/api/orchestrator/v1`
transitively through other core packages and also generates its own
bindings for the same files (accounts.proto etc.), proto registration
panics at startup: "file ... is already registered". Tests in the
orchestrator confirmed this.
Fix:
- buf generate now uses --path to limit core's output to
proto/orchestrator/v1/plugin_registry.proto (see new `make proto`).
- Adds a minimal MyAccount message and PluginAuthService.ListMyAccounts
RPC to plugin_registry.proto (already pushed to block/proto) so the
CLI's account picker no longer needs accounts.proto generated.
- CLI switches back to cli.Auth.ListMyAccounts; orchclient.Client drops
the Account field.
Side effect: every previously-generated orchestrator/v1 binding besides
plugin_registry is removed from this module.
