ib: jig `.data_reset_hack()` with vnc-client failover

Since apparently porting to the new docker container enforces using
a vnc password and `asyncvnc` seems to have a bug/mis-config whenever
i've tried a pw over a wg tunnel..?

Soo, this tries out the old `i3ipc`-win-focus + `xdo` click hack when
the above fails.

Deats,
- add a mod-level `try_xdo_manual()` to wrap calling
  `i3ipc_xdotool_manual_click_hack()` with an oserr handler, ensure we
  don't bother trying if `i3ipc` import fails beforehand tho.
- call ^ from both the orig case block and the failover from the
  vnc-client case.
- factor the `+no_setup_msg: str` out to mod level and expect it to be
  `.format()`-ed.
- refresh todo around `asyncvnc` pw ish..
- add a new `i3ipc_fin_wins_titled()` window-title scanner which
  predicates input `titles` and delivers any matches alongside the orig
  focused win at call time.
- tweak `i3ipc_xdotool_manual_click_hack()` to call ^ and remove prior
  unfactored window scanning logic.
