Raylux 0.30.2: designer and runtime agree

A fix batch across the designer, the plant-floor client and the gateway.

Designer

• The designer stops drifting from the runtime. Eight display components now draw through the same code the HMI runtime ships, resolving six differences between what you designed and what your operators saw — including a tank drawn 40% full for a value the gateway had not supplied.
• Two components now work with themed colours. Their shading was built in a way that produced invalid colours for any project following a customer colour standard.

Plant-floor client

• Saved connections from a pre-rename install are migrated instead of silently lost.
• A panel powered on while the gateway is still starting no longer needs a restart — it re-checks every 15 seconds.
• The installer is about 37 MB smaller.

Gateway and Studio

• Pulling a project from the gateway now takes the server's copy or says why it will not. Previously a recovered crash snapshot could shadow a stale project while every pull reported success.
• Creating tags under the reserved diagnostics provider is refused, as renaming and deleting already were.
• Turning module accent colours off repaints immediately.
