feat(dashpay): allow claiming invitations as small as 0.003 DASH - #1553

Conversation
The invite link validation already accepted invitations down to DASH_PAY_INVITE_MIN (0.003 DASH), but the username request screen required the invite to hold the full DASH_PAY_FEE (0.03 DASH), so smaller invites dead-ended on a disabled button. Small invites (~0.005 DASH) cover identity creation, a non-contested username and 1-2 contact requests. - RequestUserNameViewModel: gate non-contested usernames from an invite on DASH_PAY_INVITE_MIN instead of DASH_PAY_FEE - Constants: make DASH_PAY_INVITE_MIN explicit (0.003) instead of derived from DASH_PAY_FEE, and fix the stale credits comment - CreditBalanceInfo: lower LOW_BALANCE from 10x to 2x MAX_OPERATION_COST so users onboarded with small invites are not shown the low-balance warning on every contact request or profile update - Fix the low-balance dialogs (send/accept contact request, save profile) proceeding on 'Maybe later' even when the balance cannot cover the operation, and SearchUserFragment sending the contact request before the balance check

Route the exit confirmation through the balance guard.
When an empty-balance user declines this dialog, showSaveReminderDialog remains true. The user can then exit, confirm the reminder, and finish() calls save() directly at Line 627. This bypasses the empty-balance block.
Call saveButton() from the positive exit-confirmation action, or centralize the balance check in a method that every save path uses.

In the past, we only had to consider invitations created by this app, but now this app could receive invitations created by other apps. |

Final validation — Phase 2 only (queue backlog)
The PR correctly adds empty-balance guards to the direct profile-save flow, but one alternate exit path still bypasses that guard. When an empty-balance user later confirms the save reminder, the activity calls save() directly and submits the profile update despite the PR's stated requirement to block credit-consuming operations.

wallet/src/de/schildbach/wallet/ui/EditProfileActivity.kt:625-628
The guarded saveButton() path correctly avoids calling save() when the balance is empty, but showSaveReminderDialog remains true in that case. If the user then exits the activity and confirms the save-changes reminder, finish() invokes save() directly, bypassing the balance check and still broadcasting the profile update. Route this confirmation through saveButton(), or through a shared guarded save method, so every profile-save path blocks an empty balance.

Problem
The invite-link validation (
TopUpRepository.validateInvitation) already accepts invitations down toDASH_PAY_INVITE_MIN(0.003 DASH), but the username request screen required the invite to hold the fullDASH_PAY_FEE(0.03 DASH). A small invite (e.g. 0.005 DASH) therefore passed link validation, walked the user through onboarding, and then dead-ended on a permanently disabled Request username button — with the explanatory balance row hidden for the non-contested invite path.In practice invitations are expected to be ~0.005–0.01 DASH, which comfortably covers identity creation, a non-contested username and 1–2 contact requests (a contact request costs ~80–90M credits; 0.005 DASH = 500M credits).
Changes
DASH_PAY_INVITE_MINinstead ofDASH_PAY_FEE. Contested usernames still requireDASH_PAY_FEE_CONTESTED(0.25) as before.DASH_PAY_INVITE_MINan explicit0.003instead of deriving it fromDASH_PAY_FEE(so future fee changes don't silently move the invite floor), and fix the stale credits comment (0.003 DASH = 300,000,000 credits, not 150,000,000).LOW_BALANCEfrom 10× to 2×MAX_OPERATION_COST(1B → 200M credits). Previously every user onboarded with a small invite was below the 0.01 DASH warning threshold and got the low balance / buy credits dialog on every single contact request, accept, and profile update. Now the warning appears only when ~2 operations worth of credits remain.DashPayUserActivity,SearchUserFragment,NotificationsFragment,EditProfileActivity): tapping Maybe later usedif (shouldWarn)to decide whether to proceed — but an empty balance also setsshouldWarn, so operations were attempted even when the balance couldn't cover them. Changed toif (!isEmpty): warn-but-allow when low, block when truly empty. (DashPayUserBottomSheetViewModelalready implemented this correctly.)sendContactRequestfired before the balance check, which double-enqueued the operation and made the check pointless. Now matches the sibling flows inDashPayUserActivityandNotificationsFragment.Result
A user claiming a ~0.005 DASH invite can now register an identity + non-contested username and perform normal operations (contact requests/accepts, profile updates) without nagging, until their credit balance genuinely runs out — at which point operations are blocked with the buy-credits dialog instead of failing on-chain.
