[BigLep]

Done Criteria

Update to use the version of filecon-pin that users a versino of Synase that is at least 0.35.1.

Why Important

This newer version of Synapse has a few important items for filecoin-pin-website:

1. createAndAdd - we should be able to remove all the preflighting we were doing of creating a dataset on pageload. This has the ability to reduce time to add file by ~30 seconds.
2. telemetry - this was added to Synapse, but we want to get it used more places so we can see if we like the way the data is plubming to Sentry.
3. latest contract versions which means only approved SPs will be used by Synapse by default. We don't need to maintain our own list on the website of approved / good performing SPs.

Notes

A synapse 0.32.x containing version of filecoin-pin will be released in filecoin-project/filecoin-pin#171

@SgtPooki : assigning this one to you as it's in line with our 2025-10-30 conversation of getting filecoin-pin-website updated as quickly as possible, particularly so we can evaluate our telemetry efforts or whether we need to do any initialization / config changes.
