fix: don't hang drive pc on undecompilable functions

toggle_view's settle predicate (lambda: app._active != before) never
fired when tabbing toward pseudocode on a function Hex-Rays can't
decompile: App._apply_decomp snaps the view back to disasm, so _active
returns to its prior value -> full 20s settle timeout (x2 in _show_decomp,
~40s for drive pc). Recognize the decomp-failed fallback as settled.

Also harden two amplifiers surfaced by the same case:
- rpcclient: the CLI socket had no read timeout and would block forever
  on any server slowness; add a bounded settimeout (IDATUI_RPC_TIMEOUT,
  default 90s) with a clear error.
- domain.decompile: pass a bounded 15s timeout and cache failures, so a
  failing decompile can't sit at the 30s client default or be re-run by
  transport retries.
