fix(id): shorten FAQ button label and use string resource for inbound liquidity

[Rovikin]

• Shorten FAQ button label from 'Pertanyaan yang Sering Diajukan (FAQ)' to 'FAQ' to fit UI constraints
• Replace hardcoded 'Inbound liquidity' string in WalletView.kt with string resource channelsview_inbound

Changes explanation:

1. FAQ button label — shortened from 'Pertanyaan yang Sering Diajukan (FAQ)' to 'FAQ' because the original translation was too long and got truncated in the UI (visible as 'Pertanyaan y...' on the button).

2. WalletView.kt — replaced hardcoded 'Inbound liquidity' string with stringResource(R.string.channelsview_inbound) which already exists in strings.xml. This also fixes the string not being translated in the Indonesian locale.

Thank you for the fix.

A few changes are needed:

• the values-id folder and its content need to be removed. Although id is the ISO code for Indonesia, Android uses in for the resource files instead (see commit 3f3db8b)
• the R.string.channelsview_inbound entry for Indonesian needs to be added to values-in/strings.xml
• the R.string.channelsview_inbound entry for English must be added to values/strings.xml (that's mandatory, it will be the default value for other languages)
