Follow-up to the Slack bot branch, improving how assistant replies read
in Slack.
## Problem
The assistant never had the workspace URL. `buildSlackAssistantPrompt`
injected the request, requester and thread context, and the agent prompt
said nothing about links, so a record it created or found came back as
plain text with no way to open it. The reply was also a single
`markdown_text` blob with `_Answered in 3s_` appended to the answer.
## Changes
**Record deep links.** `fetchWorkspaceBaseUrl` resolves the workspace
URL from `currentWorkspace { workspaceUrls }`, preferring a custom
domain over the subdomain. It runs in parallel with the existing Slack
context fetch, so no extra latency. The prompt carries the base URL plus
the `[Record Name](base/object/<objectNameSingular>/<recordId>)` rule.
When the URL cannot be resolved the prompt explicitly forbids writing
any Twenty URL, so a failed lookup degrades to plain record names rather
than invented links.
**Reply structure.** The answer now goes out as Block Kit: a `markdown`
block for the body and a `context` block for the duration, so it reads
as a footer rather than italic text tacked onto the answer.
`getSlackChatMessageBodyFields` grew a blocks variant that keeps the
message text as Slack's notification and screen-reader fallback, and
`slackUpdateMessageHandler` now falls back to plain text on
`invalid_blocks` for blocks as well as markdown.
