Settings panel grouped by section + new logo

The MCPB settings panel previously interleaved read and write toggles for each domain (Records — Read, Records — Write, Inspections — Read, Inspections — Write, ...) which made it hard to scan and easy to miss the master kill-switch. This release reorders the fields to mirror capabilities.yaml:

1. Connection — App ID, App Secret, Agency, Environment, OAuth Redirect URI, and Encryption Key (advanced).
2. Read tools — all default-on read groups: Records, Inspections, Documents, Property, People, Workflow, Fees, Reference Data, Global Search.
3. Write tools — Allow Write Tools (master switch) first, then the individual write groups (Records, Inspections, Documents, Workflow, Payments). Allow Real-Money Payments sits at the end of this section.
4. Specialty tools — Payments — Read, GIS, Reports, Admin Escape Hatch (all off by default).

Each description now leads with the section name (e.g. "Read tools — Search records, get record details...") so the grouping is visible on hosts that render fields as a flat list.

Defaults are unchanged and continue to match the enabled_groups shape of capabilities.yaml.

Changed

• manifest.json user_config field order grouped by section.
• bundle/icon.png replaced with a sharper Accela logomark (512 → 256). Used with permission.

Upgrading

• Claude Desktop: download accela-mcp-0.4.2.mcpb below and drag onto the Extensions panel — replaces 0.4.1 in place. Existing settings carry over; the new layout reorders fields without changing values.
• CLI: uv tool upgrade accela-mcp. No code changes vs 0.4.1.
