fix: add role-aware, provider-specific AI error messages and empty room validation

[sezallagwal]

Closes #68

Changes

Role-aware, provider-specific error messages (AIHandler.ts)

• Added a getConfigError(provider) helper that selects the right error message based on usage mode (Personal / Workspace) and user role (admin / regular user).
• Each AI provider path (Self Hosted, OpenAI, Gemini) now passes its specific name (e.g. "OpenAI API key or model", "Gemini API key") to the error message.
• Personal mode: directs user to /quick config.
• Workspace admin: directs to app settings.
• Workspace user: directs to contact administrator.

Empty room validation (Handler.ts)

• Added an early return with a notification when /quick ai is used in a room with no messages, instead of silently failing.

Settings cleanup (settings.ts)

• Changed all AI settings from required: true to required: false since only one provider's keys are needed at a time — the red asterisks were misleading.

Translation updates (all 5 locales)

• Replaced 6 old translation keys with 3 parameterized keys using __provider__ placeholders, plus a new AI_No_Message_Found key.
• Updated ErrorKeys array in translation.ts to match.

Pass user context (ExecuteBlockActionHandler.ts)

• Passes user to AIHandler constructor so role-based error logic works.
