Placeful 2.0.1 — voice input, dashboard & map editor fixes

Highlights

• Assistant voice input fixed — a security header silently blocked the microphone, so dictation never even asked for access. Browsers now prompt and remember your choice.
• Dashboard crash on MySQL fixed — the bookings-by-event and by-area widgets could throw a 500 under MySQL's strict group-by mode; labels now group correctly.
• Map editor link opens reliably — "Open the map editor" from the seating plan no longer navigates into a half-initialized editor.
• Availability matrix select-all ordering — selecting all seats or time slots now behaves consistently across databases.
