fix(qt): auto-close Plugins manager, read-only field styling, RLock-safe heirs persistence
GUI / plugin lifecycle: - Auto-close Electrum's native 'Electrum Plugins' manager dialog after the BAL plugin is hot-enabled. Electrum 4.7.x no longer calls the old init_qt hook, so the close is now triggered from the create_status_bar, init_menubar and load_wallet hooks (fired when reload_windows() recreates the window). - Robust dialog matching (isinstance / class name / localized window title) to cope with zipimport module-identity mismatches. - Robust dismissal of the modal dialog (reject()/done()/close()) with a retry schedule [400, 800, 1500] ms; if it still cannot be closed, fall back to bringing it to the front (showNormal/raise_/activateWindow) so it never lingers hidden in the background. Counting only visible top-levels avoids treating an already-closed dialog as still open. Read-only field styling: - Paint the locked Delivery time / Check Alive date editors and the mining-fee spinbox with a light-grey background (#f0f0f0) so the user can see at a glance that they are not editable outside the 'Build your will' wizard; the styling is cleared when the fields are made editable again. Pickle/RLock crash on 'Build will': - heirs.save() now sanitises the heirs mapping via _json_safe() before handing it to json_db.put(), which deep-copies the value. A live runtime object (holding a threading.RLock) slipping into an heir value previously raised 'TypeError: cannot pickle _thread.RLock object' and aborted the task; such values are now coerced to str and logged with their path. - init_heirs_to_locktime() coerces the locktime to a plain serializable scalar. - log_error() now accepts both a sys.exc_info() triple and a single exception instance, fixing the secondary 'TypeError object is not subscriptable' that masked the real error.
