refactor(web): source the search result bound from its protocol constant

`ConnectionHandle.sessionSearchResultLimit` mirrored
`SESSION_SEARCH_RESULT_LIMIT` as per-connection state, giving one fact two
homes in the same module and implying a transport-varying or server-negotiated
bound that the response schema's fixed `max` forbids. `SessionsService` now
reads the constant directly and its constructor drops the parameter; the
connection handle and its unreachable `/client` value re-export go away.

The import comes from the inline-safe wire layer rather than the connection
plugin's `/client` surface, which the bundle-purity gate rejects for value
imports.
