Add BADGE_WIDTH_PERCENT env var to configure badge size (#16)

Badge width relative to poster width is now configurable via
BADGE_WIDTH_PERCENT (default 20), with a hard-coded 20% minimum floor so
the badge stays readable on smaller posters. Both label styles ("percent"
circle and "woke" pill) scale consistently off the same value.
