UI Tweaks and Logging Improvements

[revett]

Resolves #155

WIP

Greptile Summary

This PR streamlines MinIO setup, revises log timestamps and level labels, and updates the corresponding UI, documentation, and tests.

• Makes MinIO the first provider option and defaults its signing region to us-east-1.
• Removes the MinIO region input while retaining endpoint configuration.
• Formats log rows with fixed-shape local timestamps and three-letter level labels.
• Updates storage and sync integration fixtures for regionless MinIO settings.

Confidence Score: 4/5

The MinIO region regression needs to be fixed before merging because existing non-default-region production installations can no longer authenticate.

Real sync and connection testing now ignore a MinIO configuration's persisted region and sign for us-east-1, while the production settings UI removes both the region field and access to the documented custom-provider alternative.

Files Needing Attention: src/settings/settings.ts, src/settings/tab.ts, styles.css

Important Files Changed

Filename	Overview
src/settings/settings.ts	Forces all MinIO requests to sign for us-east-1, breaking production configurations whose server uses another region.
src/settings/tab.ts	Removes the MinIO region field while production still hides the only proposed alternative, the custom provider.
src/storage/storage.ts	Keeps validation aligned with the new derived MinIO region, but propagates that forced region into connection testing.
src/log/log.ts	Adds tested local timestamp formatting and stable three-letter level labels.
src/log/view.ts	Uses the new timestamp and level-label helpers when rendering persisted entries.
styles.css	Tightens log-row spacing but makes message alignment depend on the configured monospace font having equal glyph advances.
docs/technical_settings.md	Documents custom provider as the route for non-default MinIO regions without noting that production users cannot select it.

MinIO signing region is forced

If a production MinIO server uses a non-default MINIO_REGION, regionFor now ignores the persisted region and signs both connection tests and sync requests for us-east-1, causing signature verification to fail with no production-visible configuration path to correct it.

Knowledge Base Used:

• Settings module
• Storage module

Level column loses fixed width

The level span now relies on three characters occupying equal space, so a theme or user configuration that resolves --font-monospace to unequal glyph widths leaves DBG, INF, WRN, and ERR messages visibly misaligned.

Suggested change

	/* Every level tag is three letters, so a single space column keeps messages aligned. */
	.geode-log-level {
	flex-shrink: 0;
	width: 4em;
	font-weight: 700;
	}
	/* Keep the level column fixed so messages align regardless of the configured font. */
	.geode-log-level {
	flex-shrink: 0;
	width: 4em;
	font-weight: 700;
	}

Knowledge Base Used: Log module
