Update Campaign Bidding Strategy - Markifact

Updates the bidding strategy of a Meta Ads campaign. For COST_CAP and LOWEST_COST_WITH_BID_CAP, adset_bid_amount is provided as an actual dollar value, NOT in cents (e.g. pass 10 for

10). Do not multiply by 100. `adset_roas_floor` (for LOWEST_COST_WITH_MIN_ROAS) is a plain decimal multiplier (e.g. 1.23 = 123% ROAS), not a currency value. IMPORTANT: `bid_amount` returned by meta_ads_get_adset_settings is raw from Meta in minor units (cents for USD, e.g. 1000 =

10) — divide by 100 before passing here.
