Update dApp to work with the single-asset balance model. (#80)

* Handle decimals, classic tx over contract invocations

* Unify calls, add some comments

* WIP: Drop sandbox mode, make updates after testing:

We have to drop sandbox mode, because we need classic Stellar
operations. The sandbox RPC server (i.e. `soroban serve`) does not
support anything but the Soroban-only `invokeHostFunction`
operation.

We'd need to simulate trustlines in the sandbox if we want this
mode available to the example dApp.

* Account balances or smn... approvals still don't work

* Add updated contract token spec

* WIP debugging :(

* Update Soroban dependencies to latest release

* Optimized token spec

* Temporarily reset stuff

* Update comments

* Revert "Temporarily reset stuff"

This reverts commit 8c4f38d85c8c9d4ba01b14372910b267098be246.

* incorporate misc. pr feedback

* update quickstart docker image

* I think we need to convert the deposit amount to stroops

* Remove double-negation

* Fix bug in convert.ts (TODO: Add unit tests here)

* Safety check that deposit amounts are positive

Even without this, `deposit` should still fail on the `xfer_from`, so it
shouldn't be an issue.

* Update dependencies to latest Soroban SDK.

* Update comments about future work

* Though we can't fix the tests entirely, we can make progress

* Fixing up comments

* Don't need the extra getPublicKey call

* add nodejs complete workflow

* disable the rust workflow so we can merge
