fix(web-ui-info): syntax error and init order crash on fresh install

Two bugs that prevented the web-ui-info default plugin from loading:

1. Orphaned `except Exception` at line 203 with no matching `try` —
   caused a SyntaxError preventing the module from importing at all.
   Removed the orphan; the outer try/except already covers the block.

2. `_get_local_ip()` called in __init__ before `_ap_mode_cache_time`
   was initialized, causing AttributeError. Moved AP mode cache field
   initialization above the `_get_local_ip()` call.
