If I am found to be disobedient (nashiz), what is the duration for the dissolution of the marriage (faskh al-nikah)?

If you are deemed rebellious (nashiz), you are deprived of financial support (nafaqa) and have no right to claim it as long as you remain rebellious. This has no relation to the annulment of the marriage (faskh al-nikah). Your insistence on rebellion and your refusal to return to your husband's obedience gives him the right to detain you until you ransom yourself from him with money.
