fix: correct panic messages and enforce sealing check in SetStreamingManager (backport #23951)

[mergify]

• Updated panic messages in SetCMS and SetCheckTxHandler to correctly reflect function names.
• Added a missing if app.sealed check in SetStreamingManager to prevent modifications after sealing.

Why?

• Ensures panic messages match function names, making debugging more straightforward.
• Aligns SetStreamingManager with the behavior of other setter methods that enforce sealing checks.
