Improved dashboard, entity blocking, compacted history, more fast paths

• Dashboard looks a lot better and now includes a new entities tab, where users can decide to disable Fulloch access on selected devices in their Home Assistant setup
• History is now compacted with bloated tool call results being cut, so the agentic loops can run on history that matters without having unneeded context
• More Regex fast paths. The agentic setup meant simple lights off commands were taking up to 5 seconds. Regex fast path means these now happen in half a second.
