Summary

This fixes Home Assistant watch_all parsing when the config value is a quoted string.

Previously, watch_all: "false" was interpreted via bool(...), which evaluates any non-empty string as True. That caused the Home Assistant adapter to treat "false" as enabled and forward events that should have been dropped when no explicit filters were configured.

What changed

• replace raw bool(extra.get("watch_all", False)) with is_truthy_value(..., default=False)
• add regression coverage for quoted "false" at initialization time
• add regression coverage to verify that "false" does not allow unfiltered event forwarding

Repro

With config equivalent to:

platforms:
homeassistant:
extra:
watch_all: "false"

the adapter previously behaved as if watch_all were enabled.
