Swaps (both reverse and forward) are displayed in the list as a tree, which can be
expanded/collapsed. When expanded, double-clicking on any of the children (regardless
of child being LN or onchain), was interacting with the incorrect item (the first few
items in the top-level list).
Consider `self.tx_item_from_proxy_row(idx.row())`.
`idx.row()` is probably a small int, e.g. `0`, and `tx_item_from_proxy_row` is just
getting that item from the top-level list.
Note that the right-click>"View ..." context menu behaves correctly, so prior to
this commit it was inconsistent with double-clicking.
e.g. this text:
"This transaction requires a higher fee, or it will not be propagated by your current server. Try to raise your transaction fee, or use a server with a lower relay fee."
is too long for a single line.

```
Note that `get_new_wallet_name` (os.listdir) can raise OSError,
and we were calling that on the main entrypoint codepath without exception-handling.
We were also calling it in the fallback codepath without exception-handling.
i.e. the GUI errored out on every startup for affected users, and without CLI usage
it was not possible to recover.
- rm the `_get_channel_ids` abstraction as each of its usages needs subtle differences.
Some code duplication is preferable in this case.
- raise exceptions in `wait_for_message`, so that callers such as the GUI can show user-feedback
- on_error/on_warning were dropping messages with temp_chan_ids if they were not stored in
`temp_id_to_id` - which was only done once the mapping was known (so the normal chan_id was known).
To fix this, we now store temp_chan_ids into `temp_id_to_id` early.
- `schedule_force_closing` only works if the chan_id is already in `channels`

If daemon.taskgroup dies
- in GUI mode, show a crash reporter window to the user,
instead of immediately stopping the whole process.
- in daemon mode, log exception and stop process, as before.
We create a tx when the dialog is created, and re-create it every time
the user moves the fee slider. However, we were not re-creating it if
the user toggles the "Final" checkbox, meaning its value was only taken
into account if the user moved the fee slider after setting the checkbox.

To reproduce: enter "." to amount_e in Send tab; then click "Save".
