chore(deps): bump snowflake-connector-python from 4.7.1 to 4.7.2

[dependabot]

Bumps snowflake-connector-python from 4.7.1 to 4.7.2.

Release notes

Sourced from snowflake-connector-python's releases.

4.7.2

• v4.7.2(Aug 6,2026)
  • Fixed a thread leak in the file transfer agent by properly shutting down ThreadPoolExecutors after PUT/GET transfers (SNOW-3556240, #2878).
  • Fixed split_statements treating // as SQL instead of a line comment, which could merge multiple statements when a // comment contained an apostrophe (SNOW-3772985).
  • Fixed large-file PUT uploads to internal Azure stages failing against the Azure 50,000-block-per-blob limit. The Azure multipart chunk size is now scaled up dynamically for very large files (mirroring the existing S3 behavior), and the default Azure chunk size was raised from 4 MB to 8 MB (consistent with S3) for better throughput (SNOW-3839943).
  • Fixed OAuth cached-credential connections failing with 250001 Invalid OAuth access token when the cached token was invalid (GS code 390303); the connector now reauthenticates silently (via refresh token if available, otherwise browser) instead of hard-failing. Also fixed fresh processes holding only a cached refresh token going straight to an interactive browser prompt instead of attempting a silent refresh first.
  • Fixed Okta/SAML authentication reporting an exhausted login_timeout as 250003: Failed to execute request: Attempted to set connect timeout to <negative value>. Obtaining the one-time token in step 4 can overshoot the login deadline, which made the remaining budget negative; it was then passed to the HTTP layer, which rejected it with an opaque ValueError. A timed-out SAML login now raises 250006 with a message naming login_timeout. Running out of budget while retrying on RefreshTokenError reports the same error instead of failing later with an AttributeError on an empty response (SNOW-3891419).
  • Fixed OAuth authorization code flow failing for accounts with uppercase letters in the account name. urlparse().hostname always returns lowercase, but the host was compared case-sensitively in _is_snowflake_as_idp, causing Snowflake-as-IdP detection to return False and raising error 251013 (client_id is empty) even for connections that don't require a client ID.

Superseded by #735, which carries this exact commit (cherry-picked unchanged) along with the other seven low-risk bumps, so staging takes one CI run instead of eight. Closing here; the bump itself is not being dropped.

@dependabot will reopen this if the batch does not land.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
