Fix `tsl_config` → `tls_config` typo across the codebase

[josecelano]

Part of EPIC: #1978 — Configuration Overhaul (schema v3.0.0)
EPIC position: Subissue #2 of 9. Depends on #1979. Must be implemented before #1640 to avoid merge conflicts on http_tracker.rs.
Spec: docs/issues/drafts/configuration-overhaul-fix-tsl-typo.md

Goal

Fix the pervasive typo tsl_config → tls_config across the entire codebase. This is a pre-existing typo (TLS, not TSL) that has propagated into ~13 Rust source files and ~8 documentation files. Since we are releasing config schema v3.0.0, this is the right time to fix it.

Background

The codebase consistently uses tsl_config instead of tls_config:

// packages/configuration/src/v2_0_0/http_tracker.rs
pub tsl_config: Option<TslConfig>,

// packages/configuration/src/v2_0_0/tracker_api.rs
pub tsl_config: Option<TslConfig>,

// packages/configuration/src/lib.rs
pub struct TslConfig { ... }

The struct name TslConfig and all field names tsl_config should be TlsConfig / tls_config. This is a purely mechanical rename with no behavioural change.

Scope

In Scope

• Rename TslConfig → TlsConfig in packages/configuration/src/lib.rs
• Rename tsl_config → tls_config in all config struct fields (HttpTracker, HttpApi)
• Rename tsl_config → tls_config in all consumers (~13 Rust files)
• Rename tsl_config → tls_config in all documentation (~8 markdown files)
• Rename packages/axum-server/src/tsl.rs → packages/axum-server/src/tls.rs
• Update all use imports referencing the old module path

Out of Scope

• Any functional changes to TLS configuration
• Changing the TLS implementation itself

Implementation Plan

ID	Task	Notes
T1	Rename TslConfig → TlsConfig struct	In packages/configuration/src/lib.rs
T2	Rename tsl_config → tls_config fields	In HttpTracker and HttpApi config structs
T3	Rename tsl.rs → tls.rs	In packages/axum-server/src/; update mod.rs
T4	Update all Rust consumers (~13 files)	Search-and-replace tsl_config → tls_config, TslConfig → TlsConfig
T5	Update all documentation (~8 files)	Search-and-replace in markdown files
T6	Run linter all and full test suite

Acceptance Criteria

• TslConfig is renamed to TlsConfig everywhere
• tsl_config is renamed to tls_config everywhere
• packages/axum-server/src/tsl.rs is renamed to tls.rs
• rg "tsl_config|TslConfig" returns zero matches
• All tests pass
• linter all exits with code 0
