perms: move perms.go into looprpc

The Lightning Node Connect (LNC) WASM client currently imports both
`looprpc` and the entire `loop` module to access `perms.go`. This
creates problems because `loop` imports `taproot-assets`, resulting in
too many symbols for the WASM build.

To fix this, we will move `perms.go`—which defines RPC endpoint
permissions—into `looprpc`. After this change, the LNC WASM client will
import only `looprpc`, while the rest of `loop` can continue importing
`taproot-assets` without affecting the LNC WASM build.
