Dexi Desktop v0.1.10 collapsible website-theme patch

Apply this patch over your existing full-runtime Dexi Desktop portable folder.
It updates only the user interface script, so your runtime engine, local model files,
link code, and portable data folder stay in place.

What changed:
- Cleaned up the header layout and fixed the title separator.
- Added collapsible sections so more tools/cards can be added later.
- Gave the Local Dexi chat area more real estate for readability.
- Kept the link code hidden by default.
- Updated wording for P2Pprivate mesh AI network participation and WOTA rewards.
- Polished the light-blue pill buttons to better match the website.
- Tuned the local chat system prompt so Dexi stays on-brand and does not invent odd product descriptions.
- Portable runtime is preferred before any installed Ollama instance.

PowerShell apply example:
Expand-Archive "$env:USERPROFILE\Downloads\dexi-desktop-ui-collapsible-theme-patch-v0.1.10.zip" -DestinationPath "C:\DexiBuild\DexiDesktopFinal\Dexi-Desktop-Windows-Portable-v0.1.7" -Force

Then run START-HERE-DEXI-DESKTOP.bat.
