feat: Make table methods awaitable by returning AwaitableResponse

[CrystalWindSnake]

Return AwaitableResponse instead of self for Tabulator JS method calls

Currently, table methods like run_table_method() return self (fluent style),
which prevents awaiting client-side execution. This makes it impossible to
sequence dependent operations or retrieve data from the client.

Changes:

• Return AwaitableResponse from methods that invoke Tabulator JS
• Allow both fire-and-forget and awaitable usage patterns
