feat(reputation): add the reputation settings screen

[grunch]

What changes and why

This is phase 5, PR 5.4 of the reputation portability plan, and the last mobile PR. It is stacked on #744 (5.3).

Settings gains a Reputation card that opens the new ReputationScreen (/reputation). The screen has:

• Import: a short explanation and a button that opens the import screen (5.3).
• Export. It appears only when the selected node's info event advertises reputation_issuer (reputationNodeSupportProvider); otherwise the screen says the node does not export.
  • Confirm. "Export my reputation" first opens a dialog that shows the user's identity as an npub and explains that the export binds this node's account to it. This is the confirmation the protocol requires before a first binding (docs(reputation): specify the reputation attestation, kind 38388 protocol#74, "Issuance", step 3). Nothing is sent if the user cancels.
  • Result. On success the attestation is shown, with a copy button and a note to switch to the target Mostro and import it there (it is also kept as pending by 5.2). A refusal from the node, such as "needs 10 completed trades and 5 ratings", is shown in the user's language.
• Moving to a new identity:
  • the user enters the new identity's npub, which is validated;
  • "Sign authorization" signs a rebind authorisation with the identity the reputation is bound to now, for this node's issuer key;
  • the result is shown to copy, either to the new device, which passes it as rebind when exporting, or into the lnp2pBot chat (feat(reputation): move a binding to a new identity lnp2pBot/bot#934).
• Full privacy mode: a notice explains why both directions are off, and the buttons are disabled.

Strings and automation ids. 13 new strings, in all seven ARB files. Seven new ids (settings.reputation, reputation.*), all attached.

Tests

test/features/reputation/reputation_screen_test.dart, 5 cases:

• Export confirmation: the dialog shows the identity's npub; Cancel sends nothing; confirming exports and shows the result.
• A node that does not export says so.
• The node's refusal is shown.
• Rebind: an invalid npub is refused, and a valid one produces the authorisation.
• Full privacy mode disables the buttons.

flutter analyze: No issues found!
flutter test:    +1501 All tests passed!   (Flutter 3.35.7)

Screenshots

Not taken: I have not run the app on a device for this change. The flows are covered by the widget tests above, and the daemon side was run end to end (MostroP2P/mostro#1027).
