feat(brews): make Brew Again navigate to pre-filled add form

Instead of immediately creating a duplicate brew via inline POST,
the Brew Again button now links to the add-brew page with query
params that pre-fill all fields (bag, grinder, grind setting,
brewer, filter paper, water volume/temp, brew time, quick notes).
This lets users review and adjust parameters before brewing.
