Does the dowry stipulated in the marriage contract include the wife's clothing and the bedroom furniture, and are all gifts presented to the wife considered part of her clothing?

The basic principle is that clothing (kiswah) is obligatory upon the husband for his wife as part of the maintenance (nafaqah (definition)), and it has no relation to the dowry (mahr). If some part of the dowry or associated gifts are designated as clothing, there is no issue, and the determinant factor is the agreement or custom.

If the contract stipulates that the dowry is a sum of money, then clothing or household furnishings are not included in it unless there is an agreement for their inclusion. If there is no agreement, the prevailing custom is the reference. So, what is customarily considered a gift is not part of the dowry, and what is customarily stipulated as part of the dowry is indeed part of it.

If a man gives a woman clothes or similar items as a gift, these are not considered part of the obligatory clothing. In case of dispute, the default is to consider them as part of the clothing; because the apparent understanding is that what the husband provides is for the obligatory clothing, not as a mere gift.
