feat(contribution): port accept-invite.vue to ContributionAmountField

Replace cadence radios, contribution input, preset chips, guidance label,
and billing summary block with a single ContributionAmountField usage.
Default contribution updated to 180 to preserve the previous $15/mo
suggested annual default (cadence-unit value now). Updated flowSummary to
format cadence-unit directly. Updated e2e selectors to use the data-testids
the component exposes and new summary copy.
