fix: tune lightning probe routing

[pwltr]

Description

Improves Lightning route selection and diagnostics.

• Bumps ldk-node-android to 0.7.0-rc.52
• Uses routeFeeMsat from LDK probe events for successful and failed probes
• Shows the returned route fee in the probing tool instead of estimating it afterward
• Preserves large shortChannelId values as strings to avoid JS precision loss in E2E reports
• Tunes node-wide scorer fee params from the ldk-node defaults with selected overrides

QA Notes

• Added/updated coverage in LightningRepoTest.kt

@pwltr the nightly probing results against this branch have been quite good. Is this PR ready to be undrafted? I suppose we also need one for bitkit-ios?

Greptile Summary

This PR updates Lightning probe routing and fee reporting. The main changes are:

• Bumps ldk-node-android to 0.7.0-rc.52.
• Passes LDK routeFeeMsat through probe outcomes and the probing UI.
• Converts failed probe shortChannelId values to strings.
• Adds node-wide scoring fee parameter overrides.
• Updates probe-related tests and changelog notes.

Confidence Score: 4/5

The probe failure channel ID schema needs to be fixed before merging.

• The repository layer now exposes failed probe channel IDs as strings.
• At least one existing reporting path still expects the old numeric shape.
• The route fee UI flow and updated tests otherwise follow the changed probe outcome data.
