style(enterprise): clean up InfluxQL spec and fix broken config links

[jstirnaman]

Summary

Formatting and style cleanup for existing Enterprise v1 documentation — not version-specific, applies to current v1.12.2 docs.

InfluxQL spec (content/enterprise_influxdb/v1/query_language/spec.md):

• Update frontmatter: improve description, remove stale v2 alias, add related: links
• Replace absolute-URL manual TOC with relative-anchor TOC
• Convert > **NOTE:** / > **Note:** callouts to > [!Note] format throughout
• Fix h5 headings in EXPLAIN ANALYZE section to h4 for correct nesting
• Fix broken anchor links (#execution-time → #execution_time, #planning-time → #planning_time)
• Fix cross-reference links in EXPLAIN ANALYZE to use absolute paths to OSS v1 spec
• Fix typos: "keywords" → "keyword", "retention polices" → "retention policies"
• Rewrite KILL QUERY section with proper #### Syntax header and combined example block
• Fix SHOW STATS headings: remove backtick-wrapping from ### \SHOW STATS FOR...`` headings
• Add [with_key_clause] to SHOW TAG KEYS grammar production and add example
• Remove trailing whitespace in SHOW SHARDS section

Config meta nodes (content/enterprise_influxdb/v1/administration/configure/config-meta-nodes.md):

• Fix 3 broken cross-references that pointed to /enterprise_influxdb/v1/administration/config-data-nodes#... (missing configure/ path segment and trailing slash) — corrected to /enterprise_influxdb/v1/administration/configure/config-data-nodes/#...

Notes

• Stacked on fix(enterprise): correct FUTURE/PAST LIMIT docs for v1.12.2 #6947 (jts-enterprise-v1.12.2-fixes) and fix(v1): publish OSS v1.12.3, defer Enterprise v1.12.3 pending GA #6945 (jts-fix-unpublish-ent-1.12.3)
• None of these changes are version-specific — they improve existing docs regardless of release
