Minimize try block scope

Only include code that can actually raise exceptions within try blocks. Move variable assignments, logging statements, and other operations that cannot fail outside of the try block to avoid accidentally catching unintended exceptions and to improve code clarity.

This practice ensures that exception handling is precise and that you only catch the specific errors you intend to handle, rather than masking unexpected failures in seemingly safe operations.

Example of what to avoid:

try:
    session = async_get_clientsession(hass)
    api = RedgtechAPI()
    access_token = await api.login(email, password)
    if access_token:
        _LOGGER.debug("Login successful, token received.")
        # ... more processing
except Exception as e:
    _LOGGER.error("Login failed: %s", e)

Better approach:

session = async_get_clientsession(hass)
api = RedgtechAPI()
try:
    access_token = await api.login(email, password)
except Exception as e:
    _LOGGER.error("Login failed: %s", e)
    return

if access_token:
    _LOGGER.debug("Login successful, token received.")
    # ... more processing

By limiting the try block to only the await api.login() call, you ensure that any exceptions from session creation or API instantiation are not accidentally caught and mishandled as login failures.
