Change default value for delta_sharing_recipient_token_lifetime_in_seconds from 0 to 31536000 (1 year)

[840]

Changes

We now restrict delta_sharing_recipient_token_lifetime_in_seconds lifetime of a token to be 1 year.

Starting December 8, 2025, all new open sharing recipient tokens will be issued with a maximum expiration of one year from the date of creation. Tokens with longer or unlimited validity can no longer be created.

The default currently is 0, which is no longer possible. This PR sets the default to 31536000 (1 year) and removes the unlimited lifetime reference in the docs.

A few comments:

• Should we set the default value in the schema customization function?
• If we submitted non-zero value, then we should get that non-zero value back when reading the data. This may lead to configuration drift...

lgtm, small change in the docs is necessary
