Ask AI about one vehicle or one customer (#405)

* Show the AI buttons for a provider connected in the catalog

The vehicle page and the work order page decided whether to offer AI from
the settings rows the removed AI settings page used to write. A provider
connected through the integrations catalog never writes those rows, so
the buttons stayed hidden on any install set up that way. Both pages now
ask isAiConfigured, the same check the document analysis uses.

* Ask AI about one vehicle or one customer

A button on the vehicle page and the customer page opens a side sheet
with a chat about that record. The server loads the record by id and
organization, the same way the page does, and hands it to the model as
text; the model has no tools, so it can only talk about what the page
already shows. Prices and payments are left out for users without
permission to read work orders. Answers stream in and are saved per user
and record once complete.

+- When showing financial data, include currency amounts
+- If a query returns no results, suggest alternative searches
+- You can run multiple queries if needed to answer a question
+- Never make up data — only report what the queries return
+- You can ONLY read data — if asked to modify data, explain that you cannot
+- Always double-quote camelCase column names in SQL
+- Do NOT add organization filters — they are applied automatically
