Add custom fee rate to wallet Send; stop showing empty fee tiers

The HD-wallet Send dialog's fee popover relied on getUniqueBitcoinFeeSpeeds falling back to all four preset tiers when rates hadn't loaded — rendering clickable tiers with no sat/vB value (and no way to send at all when the Blockbook estimate API was down). - Show loading/error status (with a Retry) in the fee popover instead of bare tiers when rates haven't loaded. - Add a "Custom" fee tier with an inline sat/vB input so users can always specify a rate, including when the estimate API is unavailable. - Disable Send when the resolved rate is < 1 and surface an inline error. - Add resolveBitcoinFeeRate + a PresetBitcoinFeeSpeed type so 'custom' is handled distinctly from the preset tiers.
